Kev qaug zog thiab puas tsuaj ntawmhigh-purity titanium pas nrigyog yam tseem ceeb uas txiav txim siab lawv lub neej kev pab. Ntau xyoo ntawm kev tshawb fawb hauv tsev thiab txawv teb chaws tau pom tias kev qaug zog tsis ua haujlwm ntawm titanium rods thiab nws txoj kev sib raug zoo nrog ntau yam metallurgical yam yog ib txoj haujlwm ntev thiab nyuaj. Vim tias cov ntaub ntawv xeem thawj zaug tau sib cais, qee qhov teeb meem tseem ceeb tsis meej txaus, thiab cov kev xav tsis sib koom ua ke txaus, daim ntawv no tsuas yog qhia qee cov lus txiav txim.
Lub neej qaug zog ntawm cov ntaub ntawv titanium feem ntau yog tib yam li lwm cov ntaub ntawv, thiab nws muaj feem xyuam rau qhov tshwm sim ntawm kev qaug zog tawg tiam thiab kev loj hlob. Cov txiaj ntsig kev tshawb fawb pom tau tias feem ntau ntawm cov kab nrib pleb yog tsim nyob rau hauv qhov chaw plam thiab nyob rau saum npoo ntawm ob tus ciam teb, thaum Ti-6AI-4V alloy, nyob rau hauv lub xeev tsis tshua muaj kev ntxhov siab, thaum Lub zog ntawm qhov zawv zawg zawg yog siab dua thaum qhov zawv zawg zawv zawg yog nyob rau hauv kev ntxhov siab.
Thaum tus nqi nucleation nce, thaum qhov ntsuas kub ntawm cov qauv nce, qhov cuam tshuam ntawm theem thiab theem b yog qhov txuas tsis muaj zog. Txhawm rau txhim kho kev ua haujlwm qaug zog, rau ntxiv rau titanium alloy tuav, nws feem ntau xav kom tau txais cov khoom zoo equiaxed ntxiv. cov ntaub so ntswg, nyiam dua dawb beta, kom txo tau qhov alpha/beta theem interface cheeb tsam. Tsis tas li ntawd, qhov nplua-grain zawv zawg yog qhov sib xws thiab lub sijhawm pub dawb yog luv luv, uas tuaj yeem txo qhov kev ntxhov siab vim los ntawm cov plugs dislocation; Meanwhile, cov nplua-grain muaj zog constraining nyhuv ntawm twinning. Ntawm qhov tsis sib xws, coarse-grained Widmandarin microstructure yog nquag rau nucleation ntawm qaug zog tawg, yog li txo qhov qaug zog. Cov txiaj ntsig ntawm cov nplej loj ntawm cov khoom qaug zog ntawm Ti-6A1-4V kub du thiab notched specimens.
Thaum lub tawg yog notched thiab cov kev nyuaj siab yog concentrated, cov nyhuv ntawm grain loj yog txo, vim hais tias lub neej qaug zog feem ntau yog nyob ntawm qhov tawg ntawm kev loj hlob ntawm lub sij hawm no, thiab cov kev sim ntawm cov ntshiab titanium qhia tau hais tias lub grain loj tsis muaj dab tsi ua. nrog rau qhov tawg qhov kev loj hlob.
Baoji Yusheng Hlau Technology Co., Ltd., raws li cov kws tshaj lij thiab cov chaw muag khoom ntawm high-purity titanium pas nrig, ua tsaug rau kev koom tes nrog koj. Rau cov ntsiab lus hais txog cov ntsiab lus ntawm titanium rods thiab lawv cov kev hloov kho, thov xa peb cov lus nug kom nkag siab tob.
