mengder zink. Foreliggende oppfinnelse vedrorer i særdeleshet legeringer som inneholder forholdsvis små mengder aluminium og forholdsvis store mengder zink. Selv om magnesiumlegeringer som inneholder aluminium og zink tidligere har vært fremstilt inneholder teknikkens stand intet om fremstilling av magnesiumlegeringer inneholdende aluminium og zink som har god krypholdfasthet, stopbarhet og korrosjonsmotstand i kombinasjon med hoy•flytegrense og hoy strekkfasthet • amounts of zinc. The present invention relates in particular to alloys containing relatively small amounts of aluminum and relatively large amounts of zinc. Although magnesium alloys containing aluminum and zinc have previously been produced, the state of the art contains nothing about the production of magnesium alloys containing aluminum and zinc which have good creep resistance, stopability and corrosion resistance in combination with high yield strength and high tensile strength •

The present invention relates to a magnesium alloy which, apart from unavoidable impurities, consists of 0.1 to 0.6% by weight of manganese and the rest consisting of magnesium, zinc and aluminum in a weight ratio that falls within the square ABCD, indicated in the attached drawing.
Magnesiumlegeringer inneholdende zink og aluminium som faller innenfor sammensetningene som omfattes av foreliggende oppfinnelse er vist på tegningen. Tegningen representerer et trilineært diagram av sammensetningen Mg - Zn - Al definert ved firkanten ABCD, begren-set av linjene AB, BC, CD og DA som forbinder folgende punkter: Magnesium alloys containing zinc and aluminum which fall within the compositions covered by the present invention are shown in the drawing. The drawing represents a trilinear diagram of the composition Mg - Zn - Al defined by the square ABCD, bounded by the lines AB, BC, CD and DA connecting the following points:
Magnesiumlegeringer som faller innenfor sammensetningene definert ovenfor har egenskaper som er overlegne de som er kjent fra teknikkens stand. Disse egenskaper omfatter: Magnesium alloys falling within the compositions defined above have properties superior to those known from the prior art. These characteristics include:
1. God krypholdfasthet 1. Good creep resistance
2. '"'God stopbarhet f ordi legeringen har hoy flytbårhet 2. Good stoppability because the alloy has high flowability
'sammen med lav liquidus-temperåtur og er motstands- ' 'together with low liquidus temperature and is resist- '
• dyktige mot varmekrakelering. • good against thermal cracking.
3« God korrosjonsmotstand. 3« Good corrosion resistance.
i+. Hoy flytegrense. i+. High yield point.
5. Hoy strekkfasthet. 5. High tensile strength.
Det har vist seg at tilstedeværelsen av små mengder mangan, d.v.s. minst 0,1$ er nodvendig for å oppnå forbedret krypholdfasthet og korrosjonsmotstand i legeringen. Krypforlengelsen i prosent ble målt på provestaver med en strekkbelastning på o 351»5 kg/cm 2 i 100 timer ved 176,7°C. It has been found that the presence of small amounts of manganese, i.e. at least 0.1$ is necessary to achieve improved creep resistance and corrosion resistance in the alloy. The creep elongation in percent was measured on test rods with a tensile load of o 351.5 kg/cm 2 for 100 hours at 176.7°C.
Legeringer som faller innen denne firkant har krypforlengelse mindre enn 0, 6%. Man har også funnet at legeringer som har et aluminiuminn-hold mellom 3% og 5% i den tidligere beskrevne firkant har krypforlengelse mindre enn 0,5$*Alloys falling within this square have creep elongation less than 0.6%. It has also been found that alloys having an aluminum content between 3% and 5% in the previously described square have a creep elongation of less than 0.5$*
Legeringer innen nevnte firkant har en kombinasjon av god stopbarhet sammen med god krypholdfasthet og god korrosjonsmotstand. Alloys within the aforementioned square have a combination of good stopability together with good creep resistance and good corrosion resistance.
