Kev kho cua sov forging

Tempering quenching thiab kub kub thiab tempering coj kev kho cua sov, tus taw yog yuav tau ua lub chaw ua hauj lwm nrog txhua yam khoom zoo. Tempering: hardening tempering kev kho cua sov hu ua tempering. Rau tempering tempering no sau tseg nyob hauv lub 500-650 ntawm. Khoom ntawm quenched thiab tempered tus hlau, cov ntaub ntawv yog tom tus loj twg, lub zog, ductility thiab toughness yog zoo, nrog txhua yam khoom zoo. Tom qab quenching thiab tempering yog tempered sorbite. Tempered sorbite (tempered sorbite) yog nyob hauv tempering cov martensite uas muaj, raws li kev kho qhov muag tsom magnification 500 ~ 600 lub sij hawm qhia, tus carbides hauv ferrite Matrix distributed (nrog rau cementite) particle composite. Nws yog ib tempering ntawm cov koom haum martensite, no ntoos sib xyaw ferrite thiab carbide ntau. Ferrite muaj tau cov pa roj carbon-supersaturation, carbides carbides ruaj khov. Sov yog ib lub koom haum kuas.
