Hauv metallurgy, quenching feem ntau yog siv los ua kom tawv hlau los ntawm inducing a martensite transformation, qhov twg cov hlau yuav tsum tau txias sai heev los ntawm nws qhov taw tes eutectoid, qhov kub ntawm qhov austenite dhau los. tsis ruaj khov. … Qhov no tso cai rau quenching pib ntawm qhov kub thiab txias, ua rau cov txheej txheem yooj yim dua.
Yuav ua li cas quenching nce hardness?
Los ntawm cov txheej txheem quenching hu ua quench hardening, steel yog tsa rau qhov kub siab tshaj nws qhov kub thiab txias txias ntawm cov txheej txheem quenching. … Cov microstructures no ua rau muaj zog thiab hardness rau steel.
Puas quenching steel ua kom nws muaj zog?
Quenched-steel
Steel with a high carbon-cov ntsiab lus yuav ncav cuag lub xeev nyuaj duasteel nrog cov ntsiab lus qis carbon. Ib yam li ntawd, tempering high-carbon steel rau qhov kub thiab txias yuav tsim cov hlau uas hnyav dua li cov hlau tsis muaj cov pa roj carbon tsawg uas yog tempered ntawm tib qhov kub.
Yuav ua li cas rau cov hlau?
Quenching hauv caustics dissipates tshav kub sai heevhlau qhov chaw muaj kev pheej hmoo ntawm tawg thiab warping vim qhov sib txawv ntawm qhov kub thiab txias ntawm qhov chaw thiab nws cov tub ntxhais.
Puas quenching tib yam li hardening?
Cov ntaub ntawv tawv tawv feem ntau yog tempered lossis kev ntxhov siab los txhim kho lawv qhov ruaj khov thiab tawv. Cov hlau feem ntau xav tau aKev kho cua sov kom tau txais cov khoom siv kho kom zoo dua qub, xws li nce hardness lossis lub zog. … Quenching "freezes" lub microstructure, inducing stresses.
