Sauerwald, Eisenreich og Holum fant Sauerwald, Eisenreich and Holum found
for ca. 25 år siden at en tilsetning av mel-lom 0,05 og 2 % zirkonium til ulegert magnesium nedsatte støpekornstørrelsen ganske betraktelig og forhøyet styrkeegenskapene. Disse forskerne fastslo også at den for approx. 25 years ago that an addition of between 0.05 and 2% zirconium to unalloyed magnesium reduced the casting grain size quite considerably and increased the strength properties. These researchers also determined that the

Men det ser ut til at det for noen av on the other hand, such high-melting intermetallic compounds with zirconium, and are therefore principally separated as alloying elements in zirconium-containing magnesium alloys. But it seems that for some of

Britiske forskere har nemlig funnet at det er mulig å legere små mengder zirkonium og mangan i bestemte mengdeforhold inn i magnesium. De har derfor foreslått magnesiumlegeringer med 0,1 til 0,5 % zirkonium og 0,15 til 0,5 % mangan, hvor legeringen også kan inneholde andre legeringselementer, som f.eks. 1,25 % sink og/ eller opp til 3 % sjeldne jordmetaller. Eksempelvis ble beskrevet en magnesiumlegering med 0,76 % cerium, 0,26 % mangan og 0,31 % zirkonium. British researchers have found that it is possible to alloy small amounts of zirconium and manganese in specific proportions into magnesium. They have therefore proposed magnesium alloys with 0.1 to 0.5% zirconium and 0.15 to 0.5% manganese, where the alloy can also contain other alloying elements, such as e.g. 1.25% zinc and/or up to 3% rare earth metals. For example, a magnesium alloy with 0.76% cerium, 0.26% manganese and 0.31% zirconium was described.
Sauerwald og Eisenreich har senere og-så foreslått yttrium som kornforminskende tilsetning til ulegert magnesium og til manganholdige magnesiumlegeringer, og beskrevet magnesiumlegeringer med 0,1 til 10 % yttrium og eventuelt inntil 2,5 % mangan. Sauerwald and Eisenreich later also proposed yttrium as a grain-reducing addition to unalloyed magnesium and to manganese-containing magnesium alloys, and described magnesium alloys with 0.1 to 10% yttrium and possibly up to 2.5% manganese.
Nyere fremmede og egne undersøkelser har imidlertid vist at den kornforminskende virkning og dermed de bedrede styrkeegenskaper ved en slik yttriumtilsetning ikke er særlig vesentlig, slik at yttriumholdige magnesiumlegeringer hittil ikke har fått noen teknisk betydning. However, more recent foreign and own investigations have shown that the grain-reducing effect and thus the improved strength properties of such an addition of yttrium is not particularly significant, so that yttrium-containing magnesium alloys have so far had no technical significance.
Imidlertid ble det overraskende funnet at en yttriumtilsetning til zirkoniumholdige magnesiumlegeringer bevirker en yt-terligere kornforminskelse. En binær magnesiumlegering med 0,7 % zirkonium har i støpetilstand en midlere kornstørrelse på 0,15 mm; en ternær magnesiumlegering med 0,7 % zirkonium og 0,9 % yttrium har derimot en midlere kornstørrelse på 0,06 mm, har man funnet. Styrkeverdiene for den yttriumholdige legering ved romtemperatur er tilsvarende forhøyet. However, it was surprisingly found that an addition of yttrium to zirconium-containing magnesium alloys causes a further grain reduction. A binary magnesium alloy with 0.7% zirconium has an average grain size of 0.15 mm in the cast state; a ternary magnesium alloy with 0.7% zirconium and 0.9% yttrium, on the other hand, has an average grain size of 0.06 mm, it has been found. The strength values for the yttrium-containing alloy at room temperature are correspondingly increased.
Men særlig bemerkelsesverdig er det, som det videre ble funnet, at også legerin-genes varmefasthetsegenskaper ble for-høyet ved yttriumtilsetning. But it is particularly noteworthy, as it was further found, that the heat resistance properties of the alloys were also increased by the addition of yttrium.
Endelig viste det seg at yttrium har en hittil ukjent brannbeskyttende virkning, og dette både i magnesiumets flytende og faste tilstand. Finally, it turned out that yttrium has a hitherto unknown fire-protective effect, and this in both magnesium's liquid and solid state.
Oppfinnelsen vedrører altså en magnesiumlegering med gode styrkeegenskaper ved romtemperatur og høyere temperaturer og god brannmotstandsevne, og legeringen er karakterisert ved at den består av: The invention therefore relates to a magnesium alloy with good strength properties at room temperature and higher temperatures and good fire resistance, and the alloy is characterized by the fact that it consists of:
hvor det samlede innhold av beryllium, bly, kadmium, kalsium, cerium, kobber, sølv, tallium, thorium, vismut, sink og mangan ikke overskrider 10 %, og resten utgjøres av magnesium. where the total content of beryllium, lead, cadmium, calcium, cerium, copper, silver, thallium, thorium, bismuth, zinc and manganese does not exceed 10%, and the rest is made up of magnesium.
Magnesiumlegeringen ifølge oppfinnelsen kan bestå av 0,6-0,9 % zirkonium, 0,3-4 % yttrium og resten magnesium. Videre kan legeringen bestå av 0,1-0,5 % zirkonium, 0,3-4 % yttrium, 0,15-0,5 % mangan, eventuelt inntil 1,25 % zink, eventuelt inntil 3 % sjeldne jordmetaller og resten magnesium. The magnesium alloy according to the invention can consist of 0.6-0.9% zirconium, 0.3-4% yttrium and the rest magnesium. Furthermore, the alloy can consist of 0.1-0.5% zirconium, 0.3-4% yttrium, 0.15-0.5% manganese, optionally up to 1.25% zinc, optionally up to 3% rare earth metals and the rest magnesium .
Videre kan magnesiumlegeringen ifølge oppfinnelsen bestå av: Furthermore, the magnesium alloy according to the invention can consist of:
hvor det samlede innhold av beryllium, bly, kadmium, kalsium, cerium, kobber, sølv, tallium, thorium, vismut, sink og mangan ikke overskrider 6 %, og resten er magnesium. where the total content of beryllium, lead, cadmium, calcium, cerium, copper, silver, thallium, thorium, bismuth, zinc and manganese does not exceed 6%, and the rest is magnesium.
Av betydning er spesielt den brannbeskyttende virkning av en yttriumtilsetning ved zirkoniumholdige magnesiumlegeringer som inneholder minst én av de nevnte le-gerings-grunnstoffer, som f.eks. zink. Of particular importance is the fire-protective effect of an yttrium addition in the case of zirconium-containing magnesium alloys which contain at least one of the aforementioned alloy elements, such as e.g. zinc.
De tilsatte legeringsstoffers maksimal-mengder hvilke ifølge sakkyndige betrakt-ninger ikke bør overskrides, er for de enkel-te grunnstoffer ganske forskjellige. The maximum amounts of the added alloying substances, which according to expert considerations should not be exceeded, are quite different for the individual elements.
Selv om grunnstoffet cerium er nevnt som tilsetningslegeringsbestanddel, skal herved også innbefattes andre metaller fra gruppen sjeldne jordmetaller. Although the element cerium is mentioned as an additive alloy component, this shall also include other metals from the group of rare earth metals.
Den beskrevne forbedring av styrkeegenskapene ved romtemperatur og høyere temperaturer og av motstandsevnen mot brann ved tilsetning av yttrium i mengder av fortrinnsvis 0,3 til 4 %, finner også sted ved magnesiumlegeringer som inneholder små mengder zirkonium og mangan, dvs. legeringer med 0,1 til 0,5 % zirkonium og 0,15 til 0,5 % mangan. Disse magnesium-zirkonium-mangan-yttrium-legeringer kan forøvrig, som de tilsvarende yttriumfrie^legeringer, i tillegg inneholde inntil 1,25 % sink og/eller inntil 3% sjeldne jordmetaller. The described improvement of the strength properties at room temperature and higher temperatures and of the resistance to fire by the addition of yttrium in amounts of preferably 0.3 to 4% also takes place in magnesium alloys containing small amounts of zirconium and manganese, i.e. alloys with 0.1 to 0.5% zirconium and 0.15 to 0.5% manganese. Incidentally, these magnesium-zirconium-manganese-yttrium alloys, like the corresponding yttrium-free alloys, can also contain up to 1.25% zinc and/or up to 3% rare earth metals.
Varmefasthetsegenskapene av de ternære magnesium-zirkonium-yttrium-legeringer ble som ved de binære magnesium-zirkonium-legeringer i økende grad nedsatt ved økende tilsetning av legeringsgrunn-stoffer som f.eks. sink, kadmium osv. Når man derfor legger vekt på forbedrede varmefasthetsegenskaper, må legeringstilset-ningene av sink, kadmium, osv. holdes in-nenfor bestemte grenser, som ikke lar til-setningene få vesentlig innflytelse på forbedringen i varmefasthetsegenskaper for de ternære legeringer. The heat resistance properties of the ternary magnesium-zirconium-yttrium alloys were, as in the case of the binary magnesium-zirconium alloys, increasingly reduced by increasing the addition of alloying elements such as e.g. zinc, cadmium, etc. When emphasis is therefore placed on improved heat resistance properties, the alloy additions of zinc, cadmium, etc. must be kept within certain limits, which do not allow the additions to have a significant influence on the improvement in heat resistance properties of the ternary alloys.
Det teknisk oppnåelige fremskritt blir belyst av følgende eksempler. The technically achievable progress is illustrated by the following examples.
Eksempel 1 Example 1
Forbedringen av styrkeegenskapene for en zirkoniumholdig magnesiumlegering i støpetilstand ved romtemperatur (20° C) og høyere temperatur ved en tilsetning av yttrium vises av følgende tabell. The improvement of the strength properties of a zirconium-containing magnesium alloy in the cast state at room temperature (20° C) and higher temperature by an addition of yttrium is shown by the following table.
Ved 500° C kunne strekkgrensen ikke len ger måles. At 500° C, the tensile strength could no longer be measured.
Eksempel 2 Example 2
Mens de binære magnesium-zirkonium-legeringer, f.eks. en legering med 0,7 % zirkonium oppviser den kjente brann tilbøye-lighet som alle berylliumfrie magnesiumlegeringer, vil f.eks. en ternær magnesiumlegering med 0,7 % zirkonium og 0,9 % yttrium bare med vanskelighet komme i brann i smeltet tilstand. Som vist ved forsøk kan denne legering derfor støpes uten den kjente overstøvning med svovel. Den branned-settende virkning av en yttriumtilsetning er sogar sterkere enn den kjente virkning av en berylliumtilsetning på 0,002 %. While the binary magnesium-zirconium alloys, e.g. an alloy with 0.7% zirconium exhibits the known tendency to fire like all beryllium-free magnesium alloys, e.g. a ternary magnesium alloy with 0.7% zirconium and 0.9% yttrium only with difficulty catch fire in the molten state. As shown by experiments, this alloy can therefore be cast without the known dusting with sulphur. The fire-reducing effect of an yttrium addition is even stronger than the known effect of a beryllium addition of 0.002%.
Man undersøkte også den brannbeskyttende virkning av yttrium i fast tilstand. Støpeprøver av binær magnesiumlegering med 0,7 % zirkonium og av ternær legering med 0,7 % zirkonium og 0,9 % yttrium ble oppvarmet i 6 timer ved 575° C. Mens prø-vene av den binære legering etter oppvarm-ning viste tydelige tegn på brannskader, og lag, var prøvene av den ternære legering derimot uforandret, altså praktisk talt uten oksydasjon. The fire-protective effect of yttrium in the solid state was also investigated. Cast samples of binary magnesium alloy with 0.7% zirconium and of ternary alloy with 0.7% zirconium and 0.9% yttrium were heated for 6 hours at 575° C. While the samples of the binary alloy after heating showed clear signs of burn damage, and layers, the samples of the ternary alloy, on the other hand, were unchanged, i.e. practically without oxidation.
