ʻO ka malleability onā huila magnesiumʻO ka nui o ka hilinaʻi i ʻekolu mau kumu: ka wela hoʻoheheʻe paʻa, ka deformation rate a me ka nui o ka palaoa, no laila, ʻo ke aʻo ʻana o ka magnesium alloy forging ka mea nui i ka, pehea e hoʻomalu pono ai i ka pae wela, koho kūpono o ka deformation rate a me ka pūʻulu mana, hoʻomaʻemaʻe i ka nui o ka palaoa, etc.
ʻO ka maʻamau, hoʻopaʻa ʻia nā alloy magnesium i ka pae wela kiʻekiʻe ma lalo o ka wela o ka laina paʻa. Inā haʻahaʻa loa ka mahana forging, hiki ke hana ʻia nā māwae a palupalu, a paʻakikī ke hoʻokō ʻana i ka hana plastik. Ke hoʻohālikelike ʻia me nā hiʻohiʻona deformation ma ka lumi wela, ʻo ka hoʻololi ʻana i ka plastic o ka magnesium alloy i ka wela kiʻekiʻe ʻaʻole wale e hoʻonui i ka ʻōnaehana paheʻe akā ʻo ka paheʻe palena o ka palaoa. Hiki ke hā'awi aku i 'elua pūnaewele pahe'e maika'i. Wahi a Von Mises criterion, e hoʻololi ʻia ka hoʻololi wela kiʻekiʻe, kahi kūpono i ka hana ʻana. Ua ʻike ʻia e piʻi nui ka palaka o ka magnesium alloy ke piʻi ka mahana ma luna o 200 ℃, a ʻoi aku ka nui o ka plasticity i ka wā ma luna o 225 ℃. Eia nō naʻe, ke kiʻekiʻe loa ka mahana, ʻoi aku ma mua o 400 ℃, maʻalahi ka hana ʻana o ka corrosive oxidation a me ka palaoa.
Hoʻopili loa ka magnesium alloy i ka helu deformation. Hōʻike nā alloys Magnesium i ka thermoplasticity kiʻekiʻe ma ka liʻiliʻi deformation haʻahaʻa, a ua emi nui ka plasticity o nā alloy magnesium me ka piʻi ʻana o ka deformation rate. Akā, ʻokoʻa a me ka alumini alumini a me nā mea ʻē aʻe, ʻo ka magnesium alloy forging kekahi o nā hiʻohiʻona wela a ʻoi aku ka maikaʻi, ʻo kēlā me kēia hoʻomehana wela, hana ikaika - nā manawa, ʻoi aku ma mua o ka hoʻoulu ʻana i ka wela wela a lōʻihi ka manawa paʻa, i lalo i ka nui o ka nui, no kekahi o nā mea paʻakikī paʻakikī paʻakikī i ka hana ʻana, i nā manawa he nui e hoʻemi mālie i ka mahana forging.
Ua hōʻoia ka hoʻomaʻamaʻa ʻana e hiki ke hoʻomaikaʻi i nā kīʻaha equiaxed maikaʻi i ka hiki ke hoʻololi i ka plastic deformation o ka magnesium alloy, a ʻo ka nui maoli o ka palaoa ʻo ia ke kumu nui e hoʻoholo ai inā hiki ke hoʻopaʻa ʻia ka magnesium alloy ingot. No laila pehea e hoʻomalu ai i ka microstructure a hoʻomaʻemaʻe i ka palaoa kekahi o nā kī e hoʻomaikaʻi ai i ka malleability o ka alloy.
