Miyezo Yaukadaulo Yazinthu
GB/T 14992 Gulu ndi magiredi apamwamba-kutentha aloyi ndi intermetallic mankhwala kwa mkulu kutentha zipangizo
Kufotokozera kwa GJB 1952A kwa pepala lozizira lopiringizika la aloyi wotentha kwambiri kuti mugwiritse ntchito ndege
Njira ya HB/Z 140 Heat Treatment ya ma alloys otenthetsera kwambiri pazogwiritsa ntchito zakuthambo
Mbali
GH99 ndi Ni-Cr based precipitation hardening deformation high heat alloy, yomwe ingagwiritsidwe ntchito kwa nthawi yayitali pansi pa 900 ° C, ndipo nthawi yochepa kwambiri kutentha kumatha kufika 1000 ° C. GH99 alloy imalimbikitsidwa powonjezera chromium, cobalt, tungsten ndi molybdenum kuti ikhale yolimba, aluminiyamu ndi titaniyamu kuti apange magawo okalamba, ndi boron, cerium ndi magnesium kuti ayeretse ndi kulimbikitsa malire a tirigu. Aloyi ya GH99 ili ndi mphamvu zotentha kwambiri, kukhazikika kwa bungwe, ndipo imakhala yogwira ntchito yotentha komanso yozizira yopangira kupanga ndi kuwotcherera.GH99 ndiyoyenera kupanga zipinda zoyatsira injini ya aero-injini ndi zipinda zoyatsira mafuta ndi zigawo zina zotentha kwambiri zowotcherera.Zogulitsa zazikulu za GH99 ndi zowotcherera, mawaya amoto, mawaya otentha, mawaya amoto, mawaya otentha ndi ma waya. Ndi aloyi chopangidwa ndi dongosolo lalikulu mbale, angagwiritsidwe ntchito mwachindunji pambuyo njira olimba Chithandizo popanda ukalamba Chithandizo. Aloyi sichinapezeke kuti ili ndi magawo owopsa pambuyo pokalamba kwanthawi yayitali pa 700 ℃ ~ 950 ℃.
