Cov ncauj lus kom ntxaws tsom xam ntawm TC20 titanium alloy ua tshuab

I. Kev kho cua sov
Kev kho cua sov yog ib qho tseem ceeb rau kev txhim kho kev ua haujlwm ntawm TC20 titanium alloy. Cov txheej txheem kev kho cua sov uas muaj xws li annealing, daws kev kho mob thiab kev laus.
Annealing:
Lub hom phiaj: tshem tawm cov kev ntxhov siab uas nyob hauv lub sijhawm ua haujlwm, thiab kom muaj kev ruaj ntseg ntawm lub koom haum alloy.
Txoj kev:
Tsawg thiab nruab nrab kub annealing: cov hlau yog rhuab mus rau hauv qab 700 degree thiab ces cua txias. Qhov tseem ceeb uas tshwm sim nyob rau hauv cov txheej txheem no yog tshem tawm cov residual stresses, thiab cov thawj lub koom haum thiab morphology ntawm lub alloy tseem yuav luag unchanged.
Recrystallization annealing: Cov hlau yog rhuab saum qhov kub ntawm recrystallization, uas ua rau lub koom haum alloy undergo recrystallization hloov kom tau txais lub koom haum tshiab recrystallized. Qhov no pab txhim kho lub koom haum sab hauv thiab cov khoom ntawm cov khoom siv.

Solid solution kev kho mob:
Lub hom phiaj: Txhawm rau yaj cov kua hauv cov hlau los txhim kho cov plasticity thiab machinability ntawm cov hlau.
TEMPERATURE RANGE: Feem ntau ntawm 800 degree thiab 950 degree, nyob ntawm seb muaj pes tsawg leeg ntawm cov hlau thiab qhov xav tau kev txhim kho hauv cov khoom siv kho tshuab.
Sijhawm: Nyob ntawm seb muaj pes tsawg leeg ntawm cov hlau thiab qhov xav tau kev txhim kho hauv cov khoom siv kho tshuab.
Kev laus kho mob:
Lub hom phiaj: Ib kauj ruam tom qab kev daws teeb meem los tswj cov hardness thiab lub zog ntawm cov hlau los ntawm kev tswj qhov kub thiab lub sij hawm kom precipitate cov theem xav tau ntxiv dag zog.
Qhov kub thiab txias: feem ntau ntawm 450 degree thiab 650 degree, qhov kub thiab txias kuj nyob ntawm qhov tshwj xeeb muaj pes tsawg leeg ntawm cov hlau thiab cov khoom xav tau txhua yam.
Sijhawm: Ib zaug ntxiv, qhov no txawv raws li qhov xav tau tshwj xeeb.
II. Ua haujlwm txias
TC20 titanium alloy yog qhov nyuaj rau kev ua haujlwm txias vim nws lub zog siab thiab tsis tshua muaj plasticity. Cov txheej txheem ua haujlwm txias xws li txias dov, kos duab txias thiab txias forging. Thaum lub sij hawm ua hauj lwm txias, ntau yam kev kho annealing yuav tsum tau los txhim kho deformability.
Thib peb, ua haujlwm kub
Kub ua hauj lwm yog ib txoj kev tseem ceeb ntawm TC20 titanium alloy ua, uas yuav pab txo cov deformation kuj thiab txhim kho cov yas ntawm cov khoom. Cov kev ua haujlwm kub uas muaj xws li kub dov, kub forging thiab kub extrusion.
Ua haujlwm kub ntau: feem ntau ntawm 500 degree thiab 600 degree.
Nta:
Thaum lub sijhawm ua haujlwm kub, qhov saum npoo ntawm titanium alloy yog nquag tsim oxidized zaj duab xis, uas cuam tshuam rau qhov zoo ntawm cov khoom. Yog li ntawd, kev tiv thaiv feem ntau yuav tsum tau ua, xws li kev ua haujlwm hauv qhov chaw tiv thaiv lossis lub tshuab nqus tsev, los yog txheej txheej nrog cov txheej txheem tiv thaiv.
Kev ua haujlwm kub pab txhim kho lub koom haum sab hauv thiab cov khoom ntawm cov khoom siv, xws li ua kom lub zog thiab tawv ntawm cov khoom los ntawm cov nplej refinement.
IV. Lwm yam kev siv tshuab
Ntxiv nrog rau cov txheej txheem ua tiav saum toj no, kev ua tiav ntawm TC20 titanium alloy kuj tseem koom nrog lwm cov txheej txheem tshwj xeeb, xws li forging, vuam thiab lwm yam. Kev xaiv thiab kev siv cov txheej txheem no yuav tsum tau txiav txim siab raws li cov txheej txheem tshwj xeeb thiab cov khoom siv.
