Isici somkhiqizo
I-GH648 iwuhlobo lwe-Ni-Cr olusekelwe emvuleni oluqinisa ukuwohloka kwezinga lokushisa eliphezulu elinengxubevange yezinga lokushisa lesevisi yesikhathi eside elingaphansi kuka-900°C kanye nezinga lokushisa lesevisi yesikhathi esifushane elifika ku-1100°C. Ingxubevange ibonakala ngokwengezwa okungaba ngu-32% we-ω(Cr), okuwunikeza ukumelana nokugqwala okuhle kakhulu okushisayo. I-alloy ibonakala ngokungezwa cishe kuka-ω (Cr) 32%, ukuze ibe nokumelana nokugqwala okuhle kakhulu kwe-thermal. Ngesikhathi esifanayo, i-alloy inamandla aphakathi nokukhathala okuhle nokumelana nokukhasa, izindawo ezinhle zokusebenza ezibandayo kanye nezakhiwo zokushisela. Ilungele ukukhiqizwa kwezingxenye zesakhiwo ezisezingeni eliphezulu ezinezinga lokushisa elingu-900℃-1000℃ kanye nokumelana nokugqwala okuhle kakhulu. Izinhlobo eziyinhloko ezihlinzekwa ngamapuleti, imicu, imigoqo, ama-forging namaringi. Ukusebenza okuphelele kwe-alloy kungcono kunezinga lokusebenza lasekhaya le-GH3044 ne-GH3128. Ngenxa yokuthi i-GH648 ine-gravity ethize encane kune-GH3044, ingxubevange inamandla athile aphezulu.
Isicelo somkhiqizo
Ingxubevange isetshenziswe ekukhiqizeni izingxenye zegumbi elivuthayo nezinye izingxenye ezishisayo zezinjini ezithuthukisiwe ze-aero-injini, ngokukhiqizwa okuhle kwenqwaba kanye nokusetshenziswa. Amabanga afanayo asetshenziswe kabanzi ezinjinini zezindiza zakwamanye amazwe.
