Iimpawu zeMveliso
I-GH907 yimvula ye-Fe-Ni-Co eyenza lukhuni i-alloy yobushushu obuphezulu kunye nokwandiswa okuphantsi kunye nokuguqulwa, ukomelezwa nge-niobium, i-titanium, i-silicon kunye ne-trace boron. I-alloy inamandla aphezulu, i-coefficient ephantsi yokwandiswa, ukuxhathisa okulungileyo kubushushu kunye nokudinwa okubandayo kunye nemodyuli ephantse iguquguquke yokuqina ngaphantsi kwe-650 ° C. Indawo yeCurie iphakathi kwama-400°C kunye nama-4000°C. I-alloy ine-coefficient ephantsi yokwandisa kunye nokuchasana kakuhle nokukhathala okutshisa kunye nokubanda. Indawo yeCurie ikuluhlu lwe-400℃-450℃. I-coefficient yokwandiswa kwe-alloy ayitshintshi ngokuyimfuneko ngaphantsi kwe-Curie point. I-alloy ilungele ukuveliswa kwazo zonke iintlobo ze-aviation kunye ne-aerospace injini yamakhonkco kunye neemagazini ezingaphantsi kwe-650 ℃, kunye neemveliso eziphambili ziquka imivalo, i-forgings, iipleyiti kunye nemicu. Ekubeni i-alloy ingenayo i-chromium kunye ne-aluminiyam, ukuxhathisa kwe-oxidation yobushushu obuphezulu kubi. Xa isetyenziswe ixesha elide ngaphezu kwe-700 ° C, iingubo ezifanelekileyo zokukhusela kufuneka zifakwe. Umphezulu we-alloy unokudutyulwa, okuphucula ukukhathala okujikelezayo malunga ne-18%.
