Kev Tshawb Fawb Txog Rolling Txoj Kev Ua Titanium Alloy Bar
1 Cov yam ntxwv ntawm kev dov cov ntawv ntawm titanium alloy cov ntawv
Cov txheej txheem ntawm dov titanium alloy bar khoom yog tsuas yog los ntawm txias txias lub loj forged barbilletstom qab dov, thiab cov khoom txias bar feem ntau yog siv daim ntawv ntawm koob, nyias flakes lossis coarse flakes. Tom qab dov thiab txias, titanium alloy billet tuaj yeem muaj cov tawv zoo thiab lub zog, tab sis lub sijhawm no, titanium alloy bar tsis muaj cov yam ntxwv ntawm lub zog siab thiab siab plasticity. Feem ntau, kev lag luam kev lag luam yuav tsum tau ua cov txheej txheem ntawm cov titanium alloy tuav los ua tus qauv equiaxed nrog cov khoom muaj zog thiab lub zog. Txawm li cas los xij, nyob rau hauv cov txheej txheem tiag tiag dov, vim tias billet txias nyob rau ntawm chav tsev kub, cov yam ntxwv zoo ntawm cov qauv flaky raug txwv, thiab tsuas yog los ntawm cov phiaj xwm kho kom zoo nws tuaj yeem yog axed, uas tsim nyog rau kev thov hauv khw. Yog li no, microstructure axialization ntawm titanium alloy barbilletsthaum lub sij hawm dov yog qhov teeb meem tseem ceeb. Yog hais tias qhov ntau npaum li cas ntawm dov deformation loj, nws yog qhov yooj yim los txhim kho cov qauv kev sib txawv thiab cov cuab yeej lub zog. Thaum tus nqi ntawm deformation me me, nws yuav cuam tshuam rau cov khoom yas thiab lub zog ntawm titanium alloy. Nyob rau tib lub sijhawm, thaum lub sijhawm ua haujlwm dov ntawm titanium alloy pas nrig, ntau annealing tau ua. Hauv qhov no, qhov kub ntawm cov khoom ntawm cov khoom lag luam dov tau nrawm dua, thiab qhov kub ntawm sab hauv yog nce yam tsis txo, yog li ntawd cov nplaim ntawm cov khoom yob thiab qhov chaw kub ua rau muaj qhov tsis zoo, thiab tom qab ntawd yooj yim los ua rau tawg. Yog li no, yob kub yuav tsum raug tswj kom zoo. Nruab nrab ntawm cov ntawv hla, nws dhau los ua qhov chaw sib dhos uas tswj cov kub thiab txuas ntxiv mus deform. Tsuas yog los ntawm recrystallizing ib tug loj tus naj npawb ntawmtitanium alloy billettuaj yeem ua cov khoom ntawm titanium alloy pas nrig kom ua tau zoo.
