Isigaba se-eta si-ai-tungstenIkhompawundi ye-cobalt-carbon ternary eyenziwe ngokuthatha inxaxheba kwezinye iiathom ze-Co ngexesha lenkqubo yokupholisa emva kokucocai-carbide enesamente.I-W in Co enyibilikileyo ayinako ukwenza iWC.Oku kunika ithuba lonyango lwe-cryogenic ukukhuthaza ngakumbi ukubunjwa kwesigaba se-eta.ezinokubakho.
Izifundo nguReddy et al., Gill et al., Vadivel et al., Seah et al.bonke bakholelwa ukuba unyango lwe-cryogenic lubangela imvula yamasuntswana e-etai-carbide enesamente.Ubukho bezi fayiniamasuntswana e-carbideyenza i-matrix yezinto eziphathekayo ngakumbi, izinzile kwaye inzima.Ngexesha elifanayo, ngexesha lenkqubo yonyango ye-cryogenic, i-original coarse kunye ne-disordered phase particles ye-eta yahlaziywa ibe yifom ezinzileyo ye-D-22.41, 43, 4.51.
Kwizixhobo ze-carbide ezikhankanywe ngasentla, imvula yesigaba se-eta emva konyango lwe-cryogenic inokuphucula ukuqina kwayo kunye nokumelana nokunxiba ngaphandle kokuba nefuthe elikhulu kubunzima.Ngoko ke,izixhobo carbide ngesamenteemva kokuba unyango lwe-cryogenic lubonise ukusebenza okungcono kokusika.Ngokuphathelele umatshini we-eta phase precipitation, ezinye izifundo zikholelwa ukuba zihambelana nokuguqulwa kwe-martensitic eyenzeka ngexesha lokupholisa i-cryogenic, okukhokelela ekubunjweni kwesigaba kunye namaqoqo e-athomu ye-C njengondoqo ojikeleze iziphene.
