I-Incoloy A286 iyi-superalloy esekwe ku-Fe-25Ni-15Cr eqiniswe ngokwengezwa kwe-molybdenum, i-titanium, i-aluminium, i-vanadium ne-trace boron.Ngaphansi kuka-650 ℃, inamandla okukhiqiza okuphezulu, amandla ahlala isikhathi eside futhi anyakazayo, ipulasitiki enhle yokucubungula kanye nokusebenza okwanelisayo kokushisela.Ilungele ukukhiqizwa kwezinga lokushisa eliphezulu elinezingxenye zezinjini ze-aero-injini ezisebenza ngaphansi kuka-650 ℃ isikhathi eside, njenge-turbine disc, i-press disc, i-rotor blade nesixhumi, njll.Ingxubevange ingasetshenziswa ukukhiqiza imikhiqizo deformation of bobunjwa ezihlukahlukene, ezifana amapuleti, forgings, amapuleti, izinduku, izintambo kanye nezingxenye annular.Ingxubevange yekhwalithi ephezulu ye-A286 ithuthukiswa ngesisekelo se-A-286 alloy.Uma nje ukuhlanzeka kwe-alloy kuthuthukisiwe, okuqukethwe kwegesi kunqunyelwe, okuqukethwe kwezinto ezincibilikayo eziphansi kulawulwa, futhi uhlelo lokwelapha ukushisa luyalungiswa, ukuze kuthuthukiswe amandla okushisa nokusebenza kwesikhathi eside ingxubevange.
