Isici somkhiqizo
I-GH901 i-austenitic age-hardening alloy esekelwe ku-Fe-43Ni-12Cr, yengeza i-titanium, i-aluminium nezinye izakhi zokuqinisa, futhi iqukethe umkhondo we-boron nekhabhoni ephansi, nge-sub-stable γ [Ni3 (Ti, Al)] yokuqinisa ukuhlakazwa kwesigaba, inani elincane le-aluminium lingavimbela i-Tiver3γ yesigaba. Ingxubevange inamandla okukhiqiza okuphezulu namandla okubekezela angaphansi kuka-650 ℃, ukumelana okuhle kwe-oxidation ngaphansi kuka-760 ℃, kanye nokuhleleka okuzinzile ukuze kusetshenziswe isikhathi eside.
Isicelo somkhiqizo
Le ngxubevange iyingxubevange evuthiwe eyakhiwa ezinsukwini zakuqala futhi isetshenziswa kakhulu ekwenzeni izingxenye zediski ezijikelezayo (amadiski ophephela, ama-compressor disks, amajenali, njll.), izingxenye zesakhiwo ezimile, izindandatho zangaphandle zomoya ophephela, izinsimbi zokuqinisa nezinye izingxenye zezindiza nezinjini ze-turbine yegesi ephansi esebenza ngaphansi kuka-650°C. Ingxubevange isetshenziswa kabanzi ekwenzeni izinjini ze-gas turbine.
