1.Qhov lub zog ntawm Qib 2 titanium puas tuaj yeem txhim kho los ntawm kev ua haujlwm txias?
Yog lawm, lub zog ntawm Qib 2 kev lag luam ntshiab titanium tuaj yeem txhim kho tau zoo los ntawm kev ua haujlwm txias.
Qib 2 yog ib yam khoom uas tsis yog- cua sov- kho tau, txhais tau tias nws tsis tuaj yeem ntxiv dag zog los ntawm cov txheej txheem kev kho cua sov xws li kev daws teeb meem, quenching, lossis kev laus. Txawm li cas los xij, nws teb tau zoo heev rau kev ua haujlwm txias - suav nrog kev ua kom txias txias, kos duab txias, stamping, khoov, thiab swaging. Thaum lub sij hawm txias deformation, ib tug loj tus naj npawb ntawm dislocations tsim thiab multiply nyob rau hauv cov hlau microstructure, uas inhibits ntxiv yas deformation thiab ncaj qha nce yield zog, tensile zog, thiab hardness.
Raws li cov℃ntawm txias deformation nce, lub zog thiab hardness nce, thaum ductility thiab formability txo raws li. Los ntawm kev tswj hwm cov haujlwm txias, cov tuam txhab tsim khoom tuaj yeem tsim cov khoom lag luam qib 2 hauv cov tempers sib txawv kom tau raws li ntau yam kev thov. Yog li ntawd, kev ua haujlwm txias yog qhov ua tau zoo tshaj plaws thiab feem ntau siv los txhim kho lub zog ntawm qib 2 titanium.
2. Dab tsi yog qhov txwv siab tshaj ntawm qhov kev pabcuam kub rau Qib 2 titanium?
Rau kev ua haujlwm ntev -lub sij hawm txhim khu kev qha, qhov pom zoo rau kev ua haujlwm siab txuas ntxiv rau Qib 2 titanium yog kwv yees li 315℃(599℃F).
Hauv luv luv -lub sij hawm lossis tsis yog- daim ntawv thov tseem ceeb, nws tuaj yeem tiv taus qhov kub ib ntus txog li 425℃(797℃F). Nyob rau hauv tas li ntawd, muaj ntau yam teeb meem tshwm sim:
Tseem ceeb poob ntawm mechanical zog, tshwj xeeb tshaj yog creep kuj
Accelerated oxidation thiab tsim ntawm brittle nto txheej
Muaj kev pheej hmoo ntawm embrittlement vim kev nqus oxygen
Rau cov ntawv thov uas muaj qhov ntev -lub sij hawm kub siab, creep, los yog structural loading, 315℃yog dav txais raws li qhov kev nyab xeeb siab txwv nyob rau hauv engineering qauv. Yog tias xav tau kev ua haujlwm kub siab dua, cov qib alloyed titanium lossis lwm yam khoom kub - yuav tsum tau siv los hloov.
