Khoom Description
Cov txheej txheem kho cua sov rau cov hlau no yog qhov tseem ceeb hauv kev txiav txim siab lawv cov khoom kawg. Cov kws tshaj lij metallurgists ua tib zoo tswj cov cua sov thiab cua txias kom ua tiav qhov xav tau hardness, toughness, thiab lwm yam ntxwv. Qhov no feem ntau suav nrog quenching cov hlau hauv cov roj los yog dej kom txias sai sai thiab tom qab ntawd tempering nws ntawm qhov kub thiab txias kom txo cov brittleness.
Ntxiv rau lawv cov ntawv thov kev lag luam, High Vanadium Steel|A-2 Tool Steel kuj nrov ntawm cov neeg tsim riam thiab lwm cov kws ua haujlwm. Kev sib xyaw ua ke ntawm hardness thiab toughness ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev tsim cov cuab yeej txiav zoo uas tuaj yeem tiv taus kev siv hnyav thiab kev tsim txom. Qhov kev thov zoo nkauj ntawm cov hlau no, nrog rau lawv cov kev ua tiav zoo thiab cov xim hlau zoo nkauj, kuj ntxiv rau lawv qhov chaw.
