Cov hauv qab no yog cov qauv kev hloov pauv ntawm hardness ntawm AH36 steel ntawm qhov sib txawv ntawm qhov kub thiab txias, tab sis cov txiaj ntsig tshwj xeeb yuav txawv nyob ntawm qhov tshwj xeeb ntawm cov hlau, thawj lub xeev thiab lwm yam.

 

Tempering hauv qab 200 degree: Qhov kev hloov hardness tsis pom tseeb. Nyob rau hauv qhov kub thiab txias, nws yog feem ntau cov pa roj carbon segregation nyob rau hauv martensite, uas muaj ib tug kuj me me cuam tshuam rau hardness.

 

Tempering ntawm 200 degree thiab 300 degree: Rau AH36 steel, tom qab tempering nyob rau hauv no kub ntau yam, lub hardness yuav txo me ntsis, tab sis qhov txo qhov ntau yog tsis loj. Vim tias lub sijhawm no, kev hloov pauv ntawm cov austenite uas khaws cia thiab ntxiv decomposition ntawm martensite tshwm sim, thiab cov qauv tempered martensite tau tsim, tab sis cov qauv hloov pauv tsis tiav.

 

Tempering ntawm 300 degree thiab 400 degree: Lub hardness pib txo qis. Raws li qhov kub thiab txias nce mus txog 300 degree - 400 degree, cov carbides pib hloov, sib sau ua ke thiab loj hlob, decomposition ntawm martensite intensifies, thiab tetragonality txo. Cov yam tseem ceeb no ua ke ua rau txo qis hauv qhov hardness ntawm cov hlau.

Tempering ntawm 400 degree thiab 500 degree: Lub hardness tseem txo qis. Hauv qhov ntsuas kub no, theem ferrite muaj qhov pom tseeb rov qab, cov cementite maj mam sib sau ua ke thiab spheroidizes, thiab cov qauv hloov mus rau hauv tempered troostite, ntxiv txo cov hardness ntawm cov hlau.

 

Tempering ntawm 500 degree thiab 650 degree: Lub hardness ntawm cov hlau poob mus rau ib tug kuj ruaj khov theem. Lub sijhawm no, ferrite theem recrystallizes los tsim cov qauv tempered sorbite. Cov hlau muaj zoo plasticity thiab toughness, thiab hardness hloov tsis tseem ceeb piv nrog rau yav dhau los tempering theem.
