Isici somkhiqizo
I-GH4049 iyingxube ye-Ni-Co-Cr esekelwe emvuleni eyenza lukhuni deformation izinga lokushisa eliphezulu ingxubevange enezinga lokushisa lesevisi elingaphansi kuka-950℃. Ingxubevange inokumelana okuhle kwe-oxidation ngaphansi kuka-1000 ℃ namandla okushisa aphezulu angaphansi kuka-950 ℃. Ilungele ukukhiqizwa kwama-turbine e-gas ukusebenza ngezindwani ezinokushisa okusebenzayo okungu-850 ℃ ~ 950 ℃. Imikhiqizo eyinhloko ihlanganisa izinsimbi ezigoqiwe ezishisayo nezifojiwe, kanye nezindwani zezinjini zomgunyathi. Uma kuqhathaniswa nama-alloys asekelwe ku-nickel wezinhlelo zokusebenza ezifanayo, ukusebenza okushisayo kwe-alloy akusebenzi kahle, kodwa ngemva kokuncibilika kwe-electroslag noma i-vacuum arc remelting, ukucubungula kwayo kwe-plasticity kungathuthukiswa, futhi ukuqina komthelela we-1000 ℃ -1170 ℃ kukhuphuke izikhathi ezingu-1 ~ 3.
Isicelo somkhiqizo
Ingxubevange isetshenziswe ekwenzeni izinsimbi zenjini yendiza kanye nezinye izingxenye ezithwala izinga lokushisa eliphezulu. Ngemuva kwesikhathi eside sokukhiqiza nokusetshenziswa, isibe enye yezinto ezisetshenziswa kakhulu zamahlamvu.
