Isici somkhiqizo
I-GH1131 iyisixazululo esiqinile esisekelwe ku-Fe-Ni-Cr esiqiniswe ngokugoba izinga lokushisa eliphezulu ingxubevange, isixazululo esiqinile siqiniswa ngokungeza i-chromium ne-tungsten, i-molybdenum nezinye izakhi, ukusetshenziswa kwezinga lokushisa elingu-700 ℃ ~ 1000 ℃. I-alloy ine-plasticity enhle esebenzayo eshisayo, i-welding kanye nokusebenza kwenqubo ebandayo yokwenza. Imikhiqizo eyinhloko ishidi eligoqiwe elibandayo, ipuleti eligoqiwe elishisayo, ibha, insimbi eyisicaba nocingo, njll.
Isicelo somkhiqizo
I-alloy isetshenziswa kakhulu njengezingxenye zokushisa eziphezulu ze-rocket injini. Enjinini yendiza, yenziwe yaba igobolondo le-nozzle eliguquguqukayo legumbi elivuthayo kanye nocezu olulawulayo nezinye izingxenye, futhi lifakwa ekukhiqizeni. Ingasetshenziswa futhi ukwenza ku-700 ~ 1000 ℃ umsebenzi wesikhathi esifushane wenjini ye-rocket futhi ngo-700 ~ 750 ℃ umsebenzi wesikhathi eside wezingxenye ze-aero-injini ephezulu yokushisa.
