Ukonakala kwei-magnesium alloysikakhulukazi kuncike ezicini ezintathu: ingxubevange okuqinile ukuncibilika lokushisa, deformation rate kanye nosayizi okusanhlamvu, ngakho-ke, isifundo magnesium ingxubevange forging zigxile ikakhulukazi, indlela yokulawula izinga lokushisa okunengqondo uhla, ukukhethwa ezifanele izinga deformation kanye neqembu control, cwenga usayizi okusanhlamvu, njll ukwandisa noma ukuthuthukisa ikhono deformation plastic of magnesium Alloys.
Ngokuvamile, ama-alloys e-magnesium akhiwe ebangeni lokushisa eliphezulu elingaphansi kwezinga lokushisa lomugqa wesigaba esiqinile. Uma izinga lokushisa lokubumba liphansi kakhulu, imifantu ingase yakheke futhi ibe brittle, futhi kunzima ukwenza ukucubungula kwepulasitiki. Uma kuqhathaniswa nezici ze-deformation ekamelweni lokushisa, ukuguqulwa kwepulasitiki ye-magnesium alloy ekushiseni okuphezulu akukhulisi nje uhlelo lokushelela kodwa futhi nokushelela komngcele wokusanhlamvu. Isiliphu somngcele wokusanhlamvu singanikeza ezinye izinhlelo ezimbili ezisebenzayo zokushelela. Ngokuka-Von Mises criterion, i-alloy izoshintsha izinga lokushisa eliphezulu, elivumela ukwakheka. Kutholakala ukuthi ipulasitiki ye-magnesium alloy ikhuphuka kakhulu lapho izinga lokushisa lingaphezu kuka-200 ℃, futhi ipulasitiki ikhula nakakhulu lapho izinga lokushisa lingaphezu kuka-225 ℃. Kodwa-ke, uma izinga lokushisa liphezulu kakhulu, ikakhulukazi ngaphezu kuka-400 ℃, i-corrosive oxidation kanye nokusanhlamvu okuqinile kulula ukwenzeka.
I-Magnesium alloy izwela kakhulu izinga lokuguqulwa. Ama-alloys e-Magnesium akhombisa i-thermoplasticity ephezulu ngezinga eliphansi lokuguquguquka, futhi ipulasitiki ye-magnesium alloys yehla kakhulu ngokwenyuka kwezinga lokuguquguquka. Kodwa ingxubevange ye-aluminium ehlukile kanye nezinye izinto, ukubumba kwe-magnesium ingxubevange kungenye yezici izikhathi ezishisayo zokubumba ezingezinhle futhi zingaphezu kwamandla, zonke izinto zokufudumeza, ukusebenza kwamandla - izikhathi, ikakhulukazi ngaphambi kokubumba izinga lokushisa eliphezulu kanye nesikhathi sokubamba side, phansi ngezinga elikhulu, kwezinye ze-magnesium alloy forgings eziyinkimbinkimbi ukuze zakhe, izikhathi eziningi kufanele zinciphise kancane kancane izinga lokushisa.
Ukuzijwayeza kufakazele ukuthi okusanhlamvu okuhle kwe-equiaxed kungathuthukisa ikhono lokuguga lepulasitiki le-magnesium alloy, futhi usayizi wangempela wokusanhlamvu ubuye abe yisici esiyinhloko esinquma ukuthi ingot ye-magnesium alloy ingakhiwa ngokuqondile. Ngakho-ke indlela yokulawula i-microstructure futhi ucwengisise okusanhlamvu kungenye yezihluthulelo zokuthuthukisa ukusebenziseka kalula kwe-alloy.
