Tempering yog txoj kev siv los txo qhov nyuaj, yog li ua kom cov ductility ntawm cov hlau quenched, kom muab qee qhov springiness thiab malleability rau cov hlau. Qhov no tso cai rau cov hlau khoov ua ntej tawg.
kev npau taws yog vim li cas?
Tempering, hauv metallurgy, txheej txheem ntawm kev txhim kho cov yam ntxwv ntawm cov hlau, tshwj xeeb tshaj yog hlau, los ntawm cua sov rau qhov kub siab, txawm tias qis dua qhov melting point, ces txias nws, feem ntau hauv huab cua. Cov txheej txheem muaj cov nyhuv toughening los ntawm kev txo qis brittleness thiab txo cov kev ntxhov siab sab hauv.
Lub hom phiaj tseem ceeb ntawm kev npau taws yog dab tsi?
Tempering txo cov tawv tawv hauv cov khoom thiab ua kom tawv tawv. Los ntawm tempering koj tuaj yeem hloov kho cov khoom siv (hardness / toughness ratio) rau ib daim ntawv thov.
Vim li cas tempering yog ua li cas yog txawv theem ntawm tempering piav?
Tempering yog txheej txheem ntawm cua sov cov hlau tawv kom kub siab tshaj plaws mus rau qhov kub thiab txias (A 1), soaking ntawm no qhov kub thiab txias, thiab tom qab ntawd txias, feem ntau qeeb heev. Lub tempering kub yog txiav txim los ntawm lub zog (los yog hardness) thiab toughness yuav tsum tau nyob rau hauv kev pab cuam rau ib daim ntawv thov.
Lub hom phiaj ntawm tempering siab carbon steel yog dab tsi?
Tempering feem ntau yog siv tom qab quenching lag luamCua sov cov pa roj carbon steel thiab ceev ceev quenching nws tuaj yeem ua rau nws nyuaj thiab nkig. Tempering nws tuaj yeem kho qee qhov ntawm nws cov ductility. Tempering tuaj yeem txo qhov nyuaj thiab txo qhov kev ntxhov siab ntawm cov khoom siv welded.
