Los ntawm cov txheej txheem quenching hu ua quench hardening, steel yog nce mus rau qhov kub siab tshaj nws qhov kub ntawm recrystallization thiab sai txias los ntawm cov txheej txheem quenching. … Cov microstructures no ua rau nce lub zog thiab hardnessrau cov hlau.
Puas quenching ua steel nyuaj?
Quenching piav qhia txog qhov tam sim ntawd immersion ntawm ib tug rhuab hlau rau hauv dej txias los yog roj. … Yog hais tias cov hlau yog quenched, txawm li cas los xij, cov hlau alloying raug dai rau hauv cov hmoov nplej uas ua rau lawv nyuaj dua. Cov precipitates kuj txo qhov txav ntawm dislocations uas ua rau lub hardness ntawm cov khoom.
Puas quenching thiab tempering nce hardness?
Cua sov cov khoom saum toj no qhov ntsuas kub tseem ceeb ua rau cov pa roj carbon thiab lwm yam khoom nkag mus rau hauv cov tshuaj. Quenching "freezes" microstructure, inducing kev nyuaj siab. Tshwj xeeb tom qab tempered los hloov microstructure, ua tiav qhov tsim nyog hardness thiab tshem tawm cov kev ntxhov siab.
Puas quenching nce toughness?
Quenching thiab Tempering (Q&T) tau siv ntau xyoo los hloov cov khoom siv hlau, tshwj xeeb yog lub zog thiab tawv. Thaum tempering feem ntau nce toughness, qhov tshwm sim zoo hu ua tempered martensite embrittlement (TME) paub tias tshwm sim thaum lub sijhawm Q&T.
Puas quenching tooj liab nce hardness?
Spinodal-Hardening Alloys
Cov qauv muag muag thiab cov kab nrib pleb yog tsim los ntawm kev kho cua kub kub ua raws li quenching. … A qis- kub spinodal-decomposition kho, feem ntau hu ua kev laus, yog siv los ua kom cov tawv tawv thiab lub zog ntawm cov hlau.
