Kev taw qhia txog qauv

Kev kho cua sov induction thiab quenching cua sov rau cov kav hlau yog ib txoj kev kho cua sov sai. Piv nrog rau kev kho cua sov hluav taws xob ib txwm muaj, nws muaj ntau yam zoo: cov hlau microstructure muaj cov noob zoo heev; cua sov sai rau qhov kub austenitic ua ntej quenching tsim cov qauv martensite zoo heev, thiab thaum lub sijhawm quenching, cov qauv ferrite-pearlite zoo yog tsim. Vim yog lub sijhawm luv luv ntawm kev kho cua sov induction, cov khoom me me carbide precipitate thiab tau faib sib npaug hauv cov matrix martensite zoo. Cov microstructure no yog qhov tshwj xeeb tshaj yog rau cov casings tiv taus corrosion.
