Lub malleability ntawmmagnesium alloysFeem ntau yog nyob ntawm peb yam: alloy khoom melting kub, deformation tus nqi thiab grain loj, yog li ntawd, txoj kev kawm ntawm magnesium alloy forging yog mas concentrated nyob rau hauv, yuav ua li cas tswj qhov kub thiab txias ntau yam, tsim nyog xaiv ntawm deformation tus nqi thiab cov pab pawg neeg tswj, refine lub grain loj, thiab lwm yam kom nce los yog txhim kho lub peev xwm ntawm yas deformation ntawm magnesium alloys.
Feem ntau, magnesium alloys yog forged nyob rau hauv high kub ntau yam hauv qab no cov khoom-theem kab kub. Yog tias qhov kub ntawm forging tsawg dhau, cov kab nrib pleb yuav raug tsim thiab nkig, thiab nws nyuaj rau kev ua cov yas. Piv nrog rau cov yam ntxwv deformation ntawm chav tsev kub, cov yas deformation ntawm magnesium alloy ntawm qhov kub thiab txias tsis tsuas yog ua rau cov kab nrib pleb, tab sis kuj tseem ua rau cov kab lis kev cai. Cov qoob loo ciam teb tuaj yeem muab ob txoj haujlwm ua haujlwm zoo. Raws li Von Mises cov txheej txheem, cov hlau yuav raug hloov pauv kub, uas yog qhov tsim nyog rau kev tsim. Nws tau pom tias cov yas ntawm magnesium alloy nce ntau thaum qhov kub siab tshaj 200 ℃, thiab cov yas yuav nce ntxiv thaum kub siab tshaj 225 ℃. Txawm li cas los xij, thaum kub siab dhau, tshwj xeeb tshaj yog tshaj 400 ℃, corrosive oxidation thiab coarse grain yog ib qho yooj yim tshwm sim.
Magnesium alloy yog rhiab heev rau tus nqi deformation. Magnesium alloys qhia siab thermoplasticity ntawm tsawg deformation tus nqi, thiab cov yas ntawm magnesium alloys txo qis nrog qhov nce ntawm deformation tus nqi. Tab sis sib txawv thiab txhuas alloy thiab lwm yam khoom, magnesium alloy forging yog ib qho ntawm cov yam ntxwv kub forging lub sij hawm yog unfavorable thiab ntau dhau, txhua lub cua sov forging, lub zog kev ua tau zoo - lub sij hawm, tshwj xeeb tshaj yog ua ntej forging kub cua sov thiab tuav lub sij hawm ntev, down qhov loj, rau ib co ntawm cov complex magnesium alloy forgings rau txoj kev, ntau zaus yuav tsum maj mam txo tag nrho cov forging kub.
Kev xyaum tau ua pov thawj tias cov nplej zoo equiaxed tuaj yeem txhim kho cov yas deformation muaj peev xwm ntawm magnesium alloy, thiab qhov loj ntawm cov nplej kuj yog qhov tseem ceeb txiav txim siab seb magnesium alloy ingot tuaj yeem ncaj qha forged. Yog li yuav ua li cas tswj cov microstructure thiab ua kom zoo dua cov nplej yog ib qho ntawm cov yuam sij los txhim kho cov malleability ntawm cov hlau.
