Puas annealing hardening?
Annealing: Annealing yog tus txheej txheem ntawm softening cov khoom kom tau raws li cov tshuaj thiab lub cev yam ntxwv. Hardening: Hardening los yog quenching yog txheej txheem ntawm kev nce hardness ntawm cov khoom.
Puas annealing nce ua hauj lwm hardening?
Lub kab laum tsis muaj teeb meem tuaj yeem tsim lossis rov qab los thaum twg los tau los ntawm annealing. Raws li cov khoom siv ua hauj lwm hardened nws ua saturated nrog tshiab dislocations, thiab ntau dislocations yog tiv thaiv los ntawm nucleating (ib tug tsis kam mus rau dislocation-tsim tsim).
Puas annealing txo hardness?
Annealing yog txheej txheem kev kho cua sov uas hloov lub cev thiab qee zaum kuj muaj cov khoom siv tshuaj lom neeg ntawm cov khoom kom nce ductility thiab txo qhov nyuaj rau ua kom nws ua haujlwm ntau dua.
Puas annealing ua steel nyuaj?
Annealing ua hlau ntau formable. Thaum cov hlau muaj zog dua thiab muaj zog dua, nws ua rau cov tuam txhab tsim khoom ntau dua hauv cov txheej txheem fabrication. Tsis tshua muaj kev pheej hmoo ntawm cov khoom tawg los ntawm kev khoov lossis nias.

Koj daim ntawv xaj nyiaj them yug me nyuam tseem siv tau txawm tias koj tsis ua haujlwm, txhais tau tias koj tseem tshuav cov nyiaj them txhua hli uas tsim los ntawm lub tsev hais plaub.
Lub sijhawm induction hardening qhov tob ntawm hardening yog tswj los ntawm?
Qhov tob ntawm hardening yog tswj hwm los ntawm ntsuas ntawm cov khoom siv cua sov induction, lub sijhawm ntawm daim ntawv thov thiab hardenability ntawm cov khoom. Qhov tob ntawm rooj plaub yuav tswj tau li cas? Lub sij hawm thiab qhov kub thiab txias txiav txim siab tob npaum li cas rau hauv qhov chaw hardening txuas ntxiv.
