Zoo thermal stability ntawm yas pwm

Cov duab ntawm cov yas txhaj tshuaj pwm feem ntau yog nyuaj thiab nyuaj rau txheej txheem tom qab quenching. Yog li ntawd, nws yog advisable xaiv qhov chaw nrog zoo thermal stability. Thaum cov pwm tsim thiab ua tiav los ntawm kev kho cua sov, vim qhov me me coefficient ntawm linear expansion, me me kev kho cua sov deformation, me me hloov tus nqi los ntawm qhov kub thiab txias sib txawv, ruaj khov metallographic qauv thiab pwm loj, nws tuaj yeem txo lossis tsis ua tiav rau xyuas kom meej qhov tseeb ntawm pwm loj thiab nto roughness yuav tsum tau.
