Yog hais tias ib tug hlau foundry cam khwb cia cov npib tsib xee raws alloy los ntawm poob ciab peev casting (ib hom precision casting) txheej txheem, ces cov nickel alloy peev castings yuav tau. Nickel-raws li alloy yog ib hom high alloy nrog npib tsib xee raws li cov matrix (feem ntau ntau dua 50%) thiab tooj liab, molybdenum, chromium thiab lwm yam khoom raws li 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 muaj lub zog siab thiab zoo oxidation tsis kam, corrosion kuj thiab kub tsis kam nyob rau hauv thaj tsam ntawm 650 txog 1000 ° C. Nickel-raws li alloy yog ib hom kev kub kub-resistant alloy. Nickel-raws li alloys yog subdivided rau nickel-raws li kub-resistant alloys, npib tsib xee-raws li corrosion resistant alloys, npib tsib xee-raws li hnav-resistant alloys, npib tsib xee-raws li precision alloys thiab npib tsib xee-raws li zoo li nco alloys raws li lawv lub ntsiab zog. Nickel-based superalloys, hlau-raws li superalloys thiab nickel-based superalloys yog sib sau ua ke hu ua high-temperature alloys. Yog li ntawd, nickel-based superalloys raug xa mus rau nickel-based alloys. Nickel-based superalloy series cov ntaub ntawv yog dav siv hauv aviation, aerospace, roj av, tshuaj, nuclear zog, metallurgy, marine, kev tiv thaiv ib puag ncig, machinery, electronics thiab lwm yam kev lag luam. Cov qib thiab cov kev kho cua sov xaiv rau cov khoom siv sib txawv yuav txawv.
