dab tsi yog ua tiav annealing

Cov txheej txheem ntawm kev ua kom tiav yuav tsum ua kom sov cov hlau kom siab dua AC3 los ntawm 20-30 degree thiab tswj nws ntawm qhov kub thiab txias rau lub sijhawm txaus, ua raws li qhov txias txias hauv qhov cub kom tau txais qhov sib npaug ntawm lub microstructure. Lub hom phiaj ntawm cov txheej txheem kev kho cua sov no yog txhawm rau txhim kho cov qoob loo loj, tshem tawm cov kev ntxhov siab sab hauv thiab ua haujlwm tawv, txhim kho ductility, homogenize cov tshuaj lom neeg muaj pes tsawg leeg thiab microstructure ntawm cov hlau, txhim kho lub machinability ntawm cov hlau, thiab tshem tawm cov teeb meem xws li Widmanstätten qauv thiab banded qauv. nyob rau hauv nruab nrab carbon steels.
