Lub hom phiaj tseem ceeb ntawm tua thiab tempering

Txhawm rau txo qis hauv kev ntxhov siab thiab brittleness, quenched qhov chaw muaj kev ntxhov siab zoo thiab brittleness. Yog hais tias lawv tsis tempered nyob rau hauv lub sij hawm, lawv yuav feem ntau deform los yog txawm tawg. Kho cov khoom siv kho tshuab ntawm lub workpiece. Tom qab lub workpiece yog quenched, nws muaj siab hardness thiab brittleness. Txhawm rau ua kom tau raws li qhov sib txawv ntawm kev ua haujlwm ntawm ntau lub workpieces, nws tuaj yeem hloov kho los ntawm tempering, hardness, lub zog, plasticity thiab toughness. ruaj khov workpiece loj. Cov qauv metallographic tuaj yeem ruaj khov los ntawm tempering kom ntseeg tau tias tsis muaj deformation yuav tshwm sim hauv cov txheej txheem siv tom ntej. Txhim kho qhov kev ua tau zoo ntawm qee cov hlau alloy.
