IMALI yemveliso
I-GH907 yimvula ye-Fe-Ni-Co eyenza lukhuni ukwandiswa kwe-deformation ephantsi ye-alloy yobushushu obuphezulu, bomelezwe nge-niobium, i-titanium, i-silicon kunye ne-trace boron. I-alloy inamandla aphezulu, i-coefficient ephantsi yokwandisa, ukumelana kakuhle nokudinwa okushushu kunye nokubandayo kunye nemodyuli engaguqukiyo yokuqina ngaphantsi kwe-650 ℃. Indawo yeCurie iphakathi kwe-400℃ kunye ne-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. Ngenxa yokuba i-alloy ayinayo i-chromium, izinto ze-aluminiyam, ukumelana ne-oxidation yobushushu obuphezulu kubi. Xa isetyenziswe ixesha elide elingaphezulu kwe-700℃, kufuneka yamkelwe imityana yokhuseleko efanelekileyo. Umphezulu we-alloyi unokudutyulwa, kwaye ukudinwa okujikelezayo okugoba kunokongezwa malunga ne-18% emva kokuchama kokudubula.
Isicelo semveliso
I-alloy isetyenziswe kwimeko efanelekileyo ekwenzeni iimagazini ze-aero-injini ephezulu yoxinzelelo lwe-compressor yangasemva, amakhonkco athwala imithwalo, amakhonkco akhusela ubushushu, amakhonkco okutywina amagumbi okuvutha, izihlalo ze-honeycomb kunye namakhonkco angaphandle e-turbine.
