Txawm hais tias cov khoom siv tensile ntawm cov ntaub ntawv me me ntawm cov khoom siv nws tus kheej, thiab lwm yam khoom siv tau cov txheej txheem sib txawv ntawm cov txiaj ntsig sib txawv. Muaj ntau yam cuam tshuam rau lub tensile cov khoom ntawm cov hlau, uas feem ntau yuav muab faib ua ob qho khoom siv hauv tensile ntawm cov ntaub ntawv hlau.
Ua ntej tshaj plaws, qhov xwm txheej ntawm cov khoom siv khib nyiab hlau ntawm qhov cuam tshuam ntawm cov khoom siv hlau lossis cov hlau tshwj xeeb, suav nrog cov ntaub ntawv hlau tshwj xeeb, suav nrog cov ntaub ntawv hlau, alloys intermetallic tebchaw thiab lwm yam. Hauv kev ua cov ntaub ntawv hlau, nws lub koom haum yuav cuam tshuam los ntawm qee yam kev cuam tshuam thiab kev hloov pauv. Cov khoom tshwj xeeb ntawm cov ntaub ntawv hlau feem ntau yog ua rau cov khoom siv hlau ua ntej, tab sis tom qab cov khoom siv ua haujlwm ntev dua li cov khoom siv ua haujlwm, tab sis tom qab cov khoom siv ua haujlwm ntau dua thiab muaj kev phom sij ntau ntawm pob zeb. 2. Nyob rau hauv qhov kev txiav txim ntawm load sab nraud quab yuam sab nraud, cov khoom siv hlau nthuav tawm cov ****** deformation thiab tsis txhob raug puas muaj peev xwm uas yog cov yas ntawm cov khoom siv hlau. Qhov zoo dua cov plasticity ntawm cov khoom me me, nws tuaj yeem tsim cov yas deformation kom ntxiv dag zog rau lub zog ntawm cov khoom siv hlau, nce kev nyab xeeb ntawm cov khoom siv hlau.3. Hardness feem ntau yog hais txog qhov tsis kam ntawm cov khoom siv hlau ua rau lub zog tawv nias rau hauv nws cov npoo av, yog ib qho ntawm cov ntsiab lus tseem ceeb los xav txog kev ua haujlwm ntawm cov khoom siv hlau. Lub hardness ntawm cov khoom siv hlau yog qhov tshwm sim ntawm kev ua ke ntawm cov kev tawm tsam rau thawj zaug deformation, feem ntau hais lus tawm, ntau dua qhov nyuaj ntawm cov khoom siv hlau, qhov zoo dua cov hnav tsis kam yuav.
Tom qab ntawd tshawb xyuas qhov cuam tshuam ntawm kev ua haujlwm ntawm cov khoom siv hlau: kev ua haujlwm nrawm, ua haujlwm kub thiab yog li ntawm cov qauv ua haujlwm sib txawv thiab yog li ntawm cov khoom siv sib txawv uas yuav ua rau cov khoom siv sib txawv, ua rau cov khoom siv hluav taws xob sib txawv thiab yog li ntawm cov qauv ua haujlwm sib txawv thiab yog li ntawm cov qauv ua haujlwm sib txawv thiab yog li ntawm cov khoom siv sib txawv, ua rau cov qauv sib txawv thiab yog li ntawm cov khoom siv sib txawv tuaj yeem txhim kho lub zog tensile ntawm cov workpiece. 1. Feem ntau, nrog kev nce ntawm moulding kub, lub zog molecular ntawm kev muaj peev xwm nce ntxiv, ua rau kev nce qib ua ntej ntxiv tom qab kev nyiam ua kom pluav. 2 Nyob rau sab hauv cov ntaub ntawv sab hauv yog feem ntau muaj cov dislocations thiab lwm yam khoom siv kub trystalline yog feem ntau nyob rau theem ntug kev nyab xeeb thiab theem ntawm cov yas deformation. Ntawm lawv, cov khoom siv yas yas ntawm cov khoom siv hlau tsuas yog ua kom cov khoom siv hlau nplaum ua kom tiav, nws yuav ua rau cov khoom siv hlau nplaum, nws yuav ua rau cov khoom siv hlau nplaum ua kom tiav rau qhov nce ntawm lub tensile nce. 3. Qhov ntsuas kub ntawm cov khoom siv hauv cov txheej txheem ntawm cov roj stamping yuav yuav tsum tau siv cov hlau tshwj xeeb, thiab ua rau muaj teeb meem ntawm kev sib daj sib deev ntawm lub workpiece. Ntxiv nrog rau qhov cuam tshuam rau saum npoo ua tiav ntawm cov pwm ua haujlwm, thiab qhov tseeb yuav raug txo qis, rau qhov nyiaj ntau yuav tau nqis peev rau kev txhim kho ntawm cov pwm. Cov roj uas tshwj xeeb hauv cov roj txiav tawm rau cov khoom tseem ceeb thiab tiv thaiv cov pwm ntawm cov ris thiab kua muag. Ib qho ntxiv, qhov chaw tshaj tawm yuav tsis oxidise thiab xeb nyob rau lub sijhawm luv luv ntawm kev tiv thaiv cov roj, thiab nws yuav tsis cuam tshuam rau kev plating tom qab, vuam thiab lwm yam txheej txheem.
Hauv cov ntsiab lus, hauv kev ua cov ntaub ntawv hlau, ntau yam ntawm cov khoom siv tensile, yog li ntawd nws lub zog tensile, elongation ntawm kev tawg thiab qhov chaw zoo ntawm cov khoom siv tau hloov. Kev tsim nyog ntawm cov txheej txheem pab cov lag luam los txo cov nqi thiab txhim kho cov khoom lag luam kev sib tw.
