Yeebquenching yog rhuab mus rau saum toj no qhov tseem ceeb kub, tuav lub sij hawm, thiab ces sai sai mus rau hauv lub hardening tus neeg sawv cev mus rau ib tug kub dheev poob mus rau ib tug npaum li cas tshaj qhov tseem ceeb cua txias ntawm ceev ceev, martensite yog tau raws li tsis equilibrium microstructure tshav kub txoj kev.quenching tuaj yeem ua kom lub zog thiab hardness ntawm cov hlau, tab sis txo lawv cov plasticity.Quench hardening tus neeg sawv cev feem ntau siv yog: dej, roj, alkaline thiab ntsev tov thiab lwm yam.

Cov yeeb nkab tempering yuav tau reheated quenching ntawm hlau mus rau ib tug tej yam kub, thiab ces ib tug txias txoj kev hu ua tempering.Nws lub hom phiaj yog txhawm rau tshem tawm cov kev ntxhov siab sab hauv uas tsim los ntawm quenching kom txo cov hardness thiab brittleness, kom ua tiav cov khoom siv kho mob uas xav tau.Tempering ntawm high-temperature tempering, tempering kub thiab tempering pawg.Ntxiv nrog rau quenching thiab tempering, normalizing kev sib txuas.

quenching thiab tempering yog cov yeeb nkab tseem ceeb heev ntawm cov txheej txheem kev kho cua sov thiab cov txheej txheem siv ntau heev.Quenching tuaj yeem txhim kho lub zog thiab hardness ntawm hlau.Yog tias sib txuam nrog qhov sib txawv ntawm qhov kub thiab txias, koj tuaj yeem tshem tawm (lossis txo) quenching kev ntxhov siab, tab sis kuj tau txais lub zog, hardness thiab toughness ntawm qhov sib tw, kom ua tau raws li cov kev xav tau sib txawv.Yog li ntawd, quenching thiab tempering yog inseparable ob txoj kev kho cua sov.

Conditioning yog quenching thiab siab kub tempering cua sov txheej txheem.quenched pieces feem ntau nyob rau hauv kuj loj dynamic loads ua hauj lwm, lawv dais lub nro, compression, dabtsi yog khoov, twisting los yog shearing nyhuv, tab sis kuj muaj ib co deg kev sib txhuam, yuav tsum tau ib tug tej yam degree ntawm hnav kuj thiab thiaj li nyob.Nyob rau hauv luv luv, nyob rau hauv ib tug ntau yam ntawm composite qhov chaw ua hauj lwm nyob rau hauv kev ntxhov siab.Xws li cov khoom feem ntau yog rau ntau lub tshuab thiab cov chaw ua haujlwm, xws li shafts, txuas rods, bolts, gears, thiab lwm yam, hauv cov cuab yeej siv tshuab, tsheb thiab tsheb laij teb thiab lwm yam kev lag luam uas siv ntau heev.Tshwj xeeb tshaj yog rau cov tshuab hnyav hauv kev tsim cov khoom loj quenched nrog ntau dua.Yog li ntawd, quenching thiab tempering tshav kub kev kho mob occupies ib tug tseem ceeb txoj hauj lwm.
