SIFFOFIN samfur
GH4049 ne Ni-Co-Cr tushen hazo hardening nakasawa high zafin jiki gami da sabis zafin jiki na kasa da 950 ℃. A gami yana da kyau hadawan abu da iskar shaka juriya a karkashin 1000 ℃ da high zafin jiki ƙarfi karkashin 950 ℃. Shi ne dace da samar da iskar gas turbin aiki ruwan wukake da aiki zafin jiki na 850 ℃ ~ 950 ℃. Babban samfuran sun haɗa da sandunan da aka yi birgima masu zafi da ƙirƙira, da kuma mutuƙar injin injin turbin. Idan aka kwatanta da nickel na tushen gami na irin wannan aikace-aikace, da gami ta zafi aiki plasticity ne matalauta, amma bayan electroslag remelting ko injin baka remelting, ta aiki plasticity za a iya inganta, da kuma tasiri taurin 1000 ℃ -1170 ℃ ya karu da 1 ~ 3 sau.
Aikace-aikacen samfur
An yi amfani da wannan gawa wajen kera ruwan injin turbine na jirgin sama da sauran abubuwan da ke ɗaukar zafi mai zafi. Bayan dogon lokaci na masana'antu da aikace-aikace, ya zama ɗaya daga cikin kayan da aka fi amfani da shi na ganye.
