Quenching ntawmhlau alloyyog kom sov cov hlau mus rau qhov kub siab tshaj qhov ntsuas kub tseem ceeb Ac3 (hypoeutectoid steel) lossis Ac1 (hypereutectoid steel), ua kom sov rau lub sijhawm ua kom nws tag nrho lossis ib nrab austenitized, thiab tom qab ntawd txias nws ntawm qhov kub siab tshaj qhov kub. qhov ntsuas cua txias.Cov txheej txheem kev kho cua sov yog kom txias sai rau hauv qab Ms (los yog isothermally ze rau Ms) ua martensite (los yog bainite) transformation.Cov khoom siv kho mob lossis cov txheej txheem kev kho cua sov nrog cov txheej txheem ceev ceev ntawm aluminium alloy, tooj liabhlau alloy, titanium alloy, tempered iav thiab lwm yam ntaub ntawv feem ntau hu ua quenching.
Lub hom phiaj ntawm quenching:
1) Txhim kho cov khoom siv hluav taws xob ntawm cov khoom siv hlau alloy lossis qhov chaw.Piv txwv li: txhim kho hardness thiab hnav tsis kam ntawmcuab yeej,bearings, thiab lwm yam., ua kom cov elastic txwv ntawm cov springs, kev txhim kho cov khoom txhua yam ntawm cov ncej, thiab lwm yam.
2) Txhim kho cov khoom siv lossis tshuaj lom neeg ntawm qee cov hlau tshwj xeeb.Xws li kev txhim kho corrosion tsis kam ntawm stainless hlau thiab ua kom cov hlau nplaum ruaj khov ntawm cov hlau nplaum sib nqus.
