The method relates to the use of a raw material comprising a complex cubic carbonitride containing the main part of the metals from groups IV and V of the periodic system and carbon and nitrogen to be found in the finished alloy whereby said alloy has the composition 0.86 </= XIV </= 0.99, 0.74 </= XC </= 0.83 where XIV is the molar ratio of the group IV elements of the alloy and XC is the molar ratio of carbon.

Description

15 20 25 35 469 385 2 Det har nu visat sig att man genom att vid tillverkning av titanbaserade karbonitridlegeringar använda komplexa, kubiska karbonitridråvaror som innehåller huvuddelen, före- trädesvis >90 % helst >95 % av de metaller, minst två, före- trädesvis minst tre, från grupperna IV och V jämte kol och kväve som skall ingå i den färdiga sintrade karbonitridle- geringen erhåller såväl unika strukturer som unika egenska- per i denna sintrade karbonitridlegering. Företrädesvis skall allt kväve ingå i nämnda karbonitridråvara. It has now been found that by making complex, cubic carbonitride raw materials containing the major part in the manufacture of titanium-based carbonitride alloys, preferably> 90%, preferably> 95% of the metals, at least two, preferably at least three, from groups IV and V, together with carbon and nitrogen which are to be included in the finished sintered carbonitride alloy, obtain both unique structures and unique properties in this sintered carbonitride alloy. Preferably, all nitrogen should be included in said carbonitride feedstock.

Speciellt skall av de ovan diskuterade metallerna allt titan och tantal ingå i hårdämnesràvaran enligt uppfinningen. Med fördel kan även vanadin, niob samt lämpligen också zirkonium och hafnium ingå, om de ingår i den slutliga sintrade karbonitridlegeringen. Metaller från grupp VI, Cr, Mo och W, skall, i den mån de ingår, tillsättas som multipelkarbider, enkla karbider och/eller som metall+kol, men de kan även_ ingå i råvaran enligt uppfinningen under förutsättning att råvaran förblir kubisk till sin struktur.In particular, of the metals discussed above, all titanium and tantalum shall be included in the raw material raw material according to the invention. Advantageously, vanadium, niobium and suitably also zirconium and hafnium can also be included, if they are included in the final sintered carbonitride alloy. Metals from groups VI, Cr, Mo and W, in so far as they are included, shall be added as multiple carbides, single carbides and / or as metal + carbon, but they may also be included in the raw material according to the invention provided that the raw material remains cubic to its structure.

Som nämnts erhåller man intressanta egenskaper hos en sintrad karbonitridlegering om man använder sig av de speciella råvaror som omfattas av föreliggande uppfinning.As mentioned, interesting properties of a sintered carbonitride alloy are obtained if one uses the special raw materials covered by the present invention.

Så har det exempelvis visat sig att man erhåller en karbonitridlegering med utomordentliga positiva egenskaper vid extrem finbearbetning vid svarvning med höga skärhastig- heter, >300 m/s för kolstål och làglegerade stål, och låga mätningar, <0.3 mm/varv, om man utgår från en komplex råvara med t ex sammansättningen (Tio,96,Ta0,04)(C0,78,No,22).For example, it has been found that a carbonitride alloy is obtained with excellent positive properties in extreme finishing when turning at high cutting speeds,> 300 m / s for carbon steels and low-alloy steels, and low measurements, <0.3 mm / rev, if one starts from a complex raw material with, for example, the composition (Tio, 96, Ta0.04) (C0.78, No, 22).

Effekt förstärks ytterligare om man även tillsätter vanadin, varvid formeln blir (TiO'9,Ta0,03,V0,D7)(C0'79N0'2l). Mot- svarande skär som tillverkats från enkla råvaror men med exakt samma metod och i exakt samma utrustning ger betydligt sämre egenskaper i seghetsbeteende bl.a. större spridning vid samma slitstyrkenivå. Detta medför att tillförlitlig- heten hos sådana skär är betydligt sämre, vilket gör att de är mycket sämre vid produktion med begränsad bemanning, en produktionsform som alltmer ökar i betydelse pga allt högre lönekostnader. 10 l5 20 25 30 3 469 sas En av orsakerna till detta positiva beteende har visat sig vara att man erhåller en avsevärt lägre pornivå med denna komplexa råvara jämfört med konventionella råvaror utan att tillgripa några som helst ytterligare åtgärder som t ex HIP och detta sker t o m med lägre presstryck än för konventio- nellt material. Detta är en stor tillverkningsteknisk fördel bl a på grund av minskat verktygsslitage och avsevärt lägre risk för uppkomst av ogynnsamma pressprickor.Effect is further enhanced if vanadium is also added, the formula being (TiO'9, Ta0.03, V0, D7) (C0'79NO'2l). Corresponding inserts made from simple raw materials but with exactly the same method and in exactly the same equipment give significantly worse properties in toughness behavior, e.g. greater spread at the same wear level. This means that the reliability of such inserts is significantly worse, which means that they are much worse in production with limited staffing, a form of production that is becoming increasingly important due to ever higher wage costs. 10 l5 20 25 30 3 469 sas One of the reasons for this positive behavior has been shown to be that one obtains a significantly lower porn level with this complex raw material compared to conventional raw materials without resorting to any additional measures such as HIP and this even happens with lower press pressure than for conventional material. This is a major technical advantage, partly due to reduced tool wear and a considerably lower risk of the formation of unfavorable press cracks.

Uppfinningen avser alltså ett sätt för framställning av en titanbaserad karbonitridlegering med 3-25 vikt-% bindefas baserad på Co, Ni och/eller Fe enligt vilket karbonitrid- hárdämnen av metaller från grupperna IV, V och/eller VI tillsätts i form av ovan beskrivna komplexa råvara. Denna råvara mals tillsammans med bindefaselementen plus eventuell koltillsats och mindre tillsatser med t ex TiC, TiN, TaC, VC eller kombinationer därav pga små analysavvikelser hos den komplexa råvaran varefter pressning och sintring till skär utförs enligt tidigare känd teknik.The invention thus relates to a process for producing a titanium-based carbonitride alloy with 3-25% by weight of binder phase based on Co, Ni and / or Fe according to which carbonitride hair blanks of metals from groups IV, V and / or VI are added in the form of the above-described complex raw material. This raw material is ground together with the binder phase elements plus any carbon additive and smaller additives with eg TiC, TiN, TaC, VC or combinations thereof due to small analytical deviations of the complex raw material after which pressing and sintering to inserts is performed according to prior art.

Figur 1 visar det "fönster" i sammansättningsdiagrammet för Grupp IV-Grupp V-C-N, uttrycket i molbråk, för den komplexa rávaran som uppvisat ovan angivna fördelar i hög förstoring, medan figur 2 anger var i det totala molbråksdiagrammet som detta lille emràae är beläget.Figure 1 shows the "window" in the composition diagram for Group IV-Group V-C-N, the expression in molar fraction, for the complex raw material which has shown the above advantages in high magnification, while figure 2 indicates where in the total molar fraction diagram this small area is located.

Med Grupp IV avses Ti, Zr och/eller Hf och med Grupp V avses V, Nb och/eller Ta.By Group IV is meant Ti, Zr and / or Hf and by Group V is meant V, Nb and / or Ta.

I de ovan angivna molbràken för kol och kväve kan givetvis sedvanliga mängder syre ingå, dvs substituera kol och kväve, även om det är önskvärt att hålla sådana syremängder låga <0.8 %, företrädesvis<0.5 %. Uppfinningen omfattar såväl stökiometriska som sedvanligt understökiometriska karbo- nitrider. 10 15 5 469 ass Exempel Titanbaserade karbonitridlegeringar med 14 % Ni+Co-bindefas framställdes dels med användning av en komplex råvara enligt uppfinningen, (Ti0,9o,Ta0,03,V0,07)(C0'79No,2l) dels med användning av enkla råvaror, TiN, TiC, TaC och VC. I båda fallen tillsattes förutom Co och Ni även WC och Mo2C.The above-mentioned molar fractions for carbon and nitrogen can of course include customary amounts of oxygen, ie substitute carbon and nitrogen, although it is desirable to keep such amounts of oxygen low <0.8%, preferably <0.5%. The invention comprises both stoichiometric and customary sub-stoichiometric carbonitrides. 469 ass Examples Titanium-based carbonitride alloys with 14% Ni + Co binder phase were prepared using a complex raw material according to the invention, (Ti0.9o, Ta0.03, V0.07) (C0'79No, 21) and using of simple raw materials, TiN, TiC, TaC and VC. In both cases, in addition to Co and Ni, WC and Mo2C were also added.
