Amazinga Okusebenza Okubalulekile
I-GB/T 14992 Ukuhlelwa kanye namamaki ama-alloys aphezulu okushisa kanye nezinhlanganisela ze-intermetallic zezinto ezisezingeni lokushisa eliphezulu
I-GJB 1952A Ukucaciswa kweshidi eligoqiwe elibandayo le-alloy lokushisa eliphezulu elisetshenziselwa ukusetshenziswa kwezindiza
Inqubo ye-HB/Z 140 Heat Treatment yama-alloy anezinga eliphezulu lokushisa kwezicelo ze-aerospace
Isici
I-GH99 iyingxube ye-Ni-Cr esekelwe kwezulu eyenza lukhuni ukuwohloka kwezinga lokushisa eliphezulu, engasetshenziswa isikhathi eside ngaphansi kuka-900°C, futhi isikhathi esifushane izinga lokushisa eliphezulu lingafinyelela ku-1000°C. Ingxubevange ye-GH99 iqiniswa ngokungeza i-chromium, i-cobalt, i-tungsten ne-molybdenum ukuze kuqiniswe isixazululo esiqinile, i-aluminium ne-titanium ukuze kwakhiwe izigaba eziqiniswa ukuguga, kanye ne-boron, i-cerium ne-magnesium ukuze kuhlanzwe futhi kuqinise imingcele yokusanhlamvu.I-GH99 ingxubevange inamandla aphezulu okushisa, ukwakhiwa kwe-satisfactor kanye nezakhiwo eziqinile ze-welding kanye nezakhiwo eziqinile ze-holding. Ingxubevange ye-GH99 inamandla okushisa aphezulu, ukuzinza kwenhlangano, futhi inokucubungula ngendlela egculisayo okushisayo nokubanda kanye nokusebenza kwenqubo yokushisela.I-GH99 ifanele ukwakhiwa kwamagumbi omlilo we-aero-injini evuthayo kanye namakamelo omlilo kaphethiloli kanye nezinye izingxenye zesakhiwo ezishiselwe ezishibhile ezinezinga eliphezulu. Nge-alloy eyenziwe yisakhiwo esikhulu sepuleti, ingasetshenziswa ngqo ngemuva kwesixazululo esiqinile Ukwelashwa ngaphandle kokuguga Ukwelashwa. I-alloy ayitholakalanga inezigaba eziyingozi ngemuva kokuguga isikhathi eside ku-700 ℃ ~ 950 ℃.
