Thaum lub sij hawm kos duab ntawm titanium alloys, cov txheej txheem kho cua sov yog qhov tseem ceeb los txhim kho cov plasticity thiab kev kos duab ntawm cov khoom. Hauv qab no yog qee cov txheej txheem kho cua sov tshwj xeeb uas tuaj yeem txhim kho cov khoom ntawm titanium alloys:
Cov teeb meem daws teeb meem: Qhov no feem ntau siv kev kho cua sov, feem ntau nqa tawm hauv thaj chaw beta-theem, uas nce cov vixentity ntawm cov khoom. Piv txwv li, TC4 Titanium alloy tuaj yeem ua cov kev daws teeb meem los txhim kho nws cov duab kos.
Kev Kho Mob Laus: Tom qab cov teeb meem kev kho mob, kev kho mob laus feem ntau yuav tsum tau kom muaj cov khoom siv neeg zoo dua. Kev laus kev kho mob tuaj yeem nqa tawm hauv cheeb tsam hauv cheeb tsam + ob-theem lossis hauv cov khoom siv titanium, thiab lub zog ntawm cov khoom siv kub ua kom pom kev laus kub thiab sijhawm.
Qib Nruab Nrab Kev Ua Haujlwm Nruab Nrab: Thaum lub sijhawm kos duab, analmediate anealing tuaj yeem txo cov nyhuv ua haujlwm ntawm cov nplej thiab txhim kho cov yas ntawm cov khoom. Piv txwv li, hauv cov txheej txheem kos duab ntawm tc4 titanium alloy, cov kev kho mob nruab nrab nruab nrab tuaj yeem ua rau cov khoom sib luag thiab txhim kho cov plastonity.
Ob chav Annealing: Qee qhov kev tshawb fawb tau npaj siab ntawm ob txoj kev txhawb nqa ob npaug, thiab tom qab ntawd cov txheej txheem thib ob tuaj yeem txhim kho cov khoom siv TC32 titanium alloy.
Kev tswj cov txheej txheem cua txias: hauv cov txheej txheem kho cua sov, tswj ntawm tus nqi txias yog qhov tseem ceeb kom tau txais microstred microstructure thiab cov khoom. Piv txwv li, sai sai txias tom qab kev kho mob tuaj yeem tsim martensite, thaum lub caij qeeb qeeb tau txais kev tsim cov koom haum nplua nuj.
Kev kho kom haum cua sov: lub theem muaj pes tsawg leeg, MicroY tswj qhov kub thiab txias tau cuam tshuam los ntawm kev ntsuas kub, lub sijhawm thiab cov qauv cua txias ntawm kev kho cua sov.
Cov tshuaj Txhuam: los ntawm kev tswj hwm kev loj hlob qauv ntawm cov nplej los ntawm kev kho kom zoo thiab kev laus, cov kws kho tshuab ntawm cov khoom siv ntawm TC18 titanium alloy tuaj yeem ua kom zoo.
Cawv ntawm qhov kub ntawm lub zog tensile: piv txwv li, hauv kev kos duab ntawm TC4 Titanium alloy, kev kho cua sov ntawm 700 ~ 750 degree tuaj yeem tau txais cov khoom siv zoo.
Simulation ntawm kev kho cua sov: Siv molecular dynamics rau simulate cov txheej txheem kho cua sov, qhov cuam tshuam ntawm cov khoom siv cua sov ntawm TC4 titanium alloy tuaj yeem kwv yees.
