IZINGA LOKUPHEPHA
I-GB/T 14992 Ukuhlukaniswa kanye namamaki ama-alloys aphezulu okushisa kanye nezinhlanganisela ze-intermetallic zezinto ezisezingeni lokushisa eliphezulu
I-GJB 5261 Ukucaciswa kwamabha engxubevange yokushisa okuphansi okunwebeka okuphansi
I-HB 7682 Ukunwetshwa okuphansi kwe-GH907 izinga lokushisa eliphezulu kwe-alloy ring izikhala nezingcezu zendandatho
Inqubo ye-HB/Z 140 Heat Treatment yama-alloys okushisa aphezulu ukuze kusetshenziswe indiza
I-Q/GYB 05067 GH2907 ingxubevange yeshidi eligoqiwe elibandayo kanye nomucu
I-Q/GYB 05069 Izintambo ezibandayo ze-HGH2907 alloy zokushisela
Izici Zomkhiqizo
I-GH907 iyimvula ye-Fe-Ni-Co eqinisa izinga lokushisa eliphezulu ingxubevange ngokunwebeka okuphansi kanye nokuguqulwa, iqiniswe nge-niobium, i-titanium, i-silicon kanye ne-trace boron. Ingxubevange inamandla amakhulu, i-coefficient ephansi yokwandisa, ukumelana kahle nokukhathala okushisayo nokubanda kanye nemodulus ecishe ibe njalo yokunwebeka ngaphansi kuka-650°C. Indawo yeCurie iphakathi kuka-400°C no-4000°C. I-alloy ine-coefficient ephansi yokwandisa futhi imelana kahle nokukhathala okushisayo nokubandayo. Iphoyinti le-Curie lisebangeni elingu-400℃-450℃. I-coefficient yokunwetshwa kwe-alloy empeleni ayishintshile ngaphansi kwephoyinti le-Curie. Ingxubevange ilungele ukukhiqizwa kwazo zonke izinhlobo zamasongo enjini yendiza kanye nomagazini ngaphansi kuka-650 ℃, futhi imikhiqizo eyinhloko ihlanganisa imigoqo, ama-forging, amapuleti namapheshana. Njengoba ingxubevange ingenayo izakhi ze-chromium ne-aluminium, ukumelana nokushisa okuphezulu kwe-oxidation kubi. Uma isetshenziswa isikhathi eside ngaphezu kuka-700 ° C, kufanele kufakwe izimbotshana zokuvikela ezifanele. Ingaphezulu lengxubevange lingadutshulwa, okuthuthukisa ukukhathala kokugoba okujikelezayo cishe ngo-18%.
