Hardenability thiab hardenability yog qhov ntsuas kev ua tau zoo uas ua rau muaj peev xwm quenchingZam txim, thiab lawv kuj yog cov tseem ceeb rau kev xaiv thiab siv cov ntaub ntawv.Ua kom muaj zogyog qhov siab tshaj plaws uas akev zamtuaj yeem ua tiav hauv qab qhov zoo tshaj plaws.Qhov no tseem ceeb txiav txim siab lub harthening degree ntawmkev zamyog cov ntsiab lus carbon ntawmkev zam, lossis ntau dua cov ntsiab lus carbon ntawm cov ntsiab lus carbon hauv Austenite thaum quenching thiab cua sov. Qhov siab dua cov ntsiab lus carbon yog, siab dua cov phiaj xwm harteren ntawm cov hlau muaj cov khoom siv tsis muaj zog ntawm cov hlau tsis muaj zog ntawm cov tawv nqaij tawv ntawm cov hlau.
Cov yam ntxwv nyuaj yog cov xeeb ceem uas txiav txim siab qhov tob thiab nyuaj rau cov khoom tawv uas muaj zog ntawm steel.Hogardenity ua tau zoo li cov Yooj yim nrog cov Austenite tuaj yeem hloov pauv mus rau martensite thaum cov steel yog tsuas cuam tshuam nrog kev ruaj ntseg ntawm supercooled Austenite hauv cov hlau, lossis mus rau qhov tseem ceeb Quenching tus nqi txias hauvForged Steel.

Tom qab quenching, lub mootalographic qauv thiab kev faib khoom hluav taws xob hardness yog pom ntawm cov ntoo khaub lig ntawm qhov nruab nrab txias. Ntu ntu yog martensite thiab cov khoom seem tau muab faib ua cov chaw uas tsis muaj martensite, piv txwv li cov khoom siv ua ntej, yog li nws cov tawv tawv zoo dua, Lub martensite hardness ntawm cov khoom ntawm sab laug yog siab dua, uas yog qhov chaw ua kom txias .Qhov cua txias heev. Raws li lub chaw nruab nrab ncav cuag. Yog tias qhov txias txias ntawm cov nplaim dej thiab qhov chaw ntawm kev Forging yog ntau dua qhov kev lom zem heev ntawm cov steel forging yog, cov steel forging yog ua kom tiav.if Qhov chaw nruab nrab hauv nruab nrab yog hauv qab no tus nqi txias rau hauv qab thiab tsis yog-Martensitic cov ntaub so ntswg yog tau txais hauv lub siab, qhia tias cov steel forging tsis tau quenched los ntawm.
Hauv kev tsim khoom, qhov ua tau zoo ntawm cov hlauZam tximfeem ntau yog qhia los ntawm qhov tob ntawm cov txheej hardening zoo, yog, ntim feem ntau) ntawm martensite.it kuj tseem muaj txiaj ntsig los ntsuas qhov chaw ntsug los ntawm qhov chaw nyuaj rau Qhia txog qhov tob ntawm qhov ua tau zoo txheej.Txhua qhov tob (DC) yog ntsuas los ntawm qhov chaw sov sov los ntawm saum npoo mus rau qhov kev nyuaj.
Kev faib tawm cov khoom siv kho tshuab lub zog tom qab quenching thiab tempering ntawmZam tximnrog txawv hardenability yog qhia nyob rau hauv daim duab.Hhu Hardenability ntawm nws cov khoom siv hluav taws xob ntawm lub plawv, cov tawv nqaij tawv ntawm lub plawv qis.Qhov no qis dua.Qhov no yog vim tom qab TemperedKev muag tshuaj hlauNrog rau cov neeg tawv tawv muaj zog, lawv cov qauv los ntawm saum npoo rau sab hauv yog granular tempered soxhlability, thaum muaj cov siab tawv nqaij muaj lub siab tsis muaj flemsstrhathlability.
