Nickel-raws li alloy hais txog lub siab alloy nrog npib tsib xee raws li cov matrix (feem ntau ntau dua 50%) thiab tooj liab, molybdenum, chromium thiab lwm yam khoom ua alloying ntsiab. Lub ntsiab alloying ntawm nickel-based alloys yog chromium, tungsten, molybdenum, cobalt, aluminium, titanium, boron, zirconium thiab lwm yam. Ntawm lawv, Cr, Al, thiab lwm yam feem ntau ua si ib qho kev tiv thaiv oxidation, thiab lwm yam ntsiab lus muaj cov tshuaj ntxiv dag zog, nag lossis daus ntxiv dag zog thiab grain ciam teb ntxiv zog. Nickel-based alloys feem ntau muaj cov qauv austenitic. Nyob rau hauv lub xeev ntawm kev daws teeb meem thiab kev laus kev kho mob, kuj tseem muaj cov theem intermetallic thiab hlau carbonitrides ntawm austenite matrix thiab grain ciam teb ntawm cov hlau.Nickel-based alloys feem ntau yog nrum los ntawm kev nqis peev casting txheej txheem. Cov qib sib txawv ntawm nickel-based alloys rau casting yog raws li hauv qab no:
- 1) Ni-Cr-Mo alloy, Hastelloy series C-276, C-22, C-2000, C-4, B-3
- 2) Ni-Cr alloy: Inconel 600, Inconel 601, Inconel 625, Inconel 718, Inconel X 750, Incoloy 800, Incoloy 800H, Incoloy 800HT, Incoloy 825;
- 3) Ni-Cu alloy, Monel 400, Monel K500
