Kev siv hluav taws xob siab Alloy deformation ntxiv dag zog yog siv cov txheej txheem ntawm deformation ntawm kev txhawb nqa hlau lub zog. Kuj tau paub tias yog txoj hlab tawv tawv lossis ua haujlwm tawv. Lub zog ntawm cov khoom ntawm macro (los yog tag nrho) lub peev xwm los tawm tsam deformation (lossis ntws kev ntxhov siab). Hardness yog lub peev xwm ntawm cov khoom siv los tiv thaiv cov plua plav nplaum (txawm tias Micro-hardness, vickwell hardness lossis brinell hardness). Ob qho tib si muaj kev sib raug zoo sib xws hauv ntau kis. Lub zog ntawm cov khoom, ntau dua qhov tsis kam rau cov yas deformation, ntau dua tus nqi hardness. Hloov siab, ntau dua qhov nyuaj ntawm cov khoom, cov ntaub ntawv tuaj yeem yog vim muaj zog ua kom zoo nkauj, nws lub zog tsis yog tag nrho cov nqi index zoo li tsis muaj zog.
Txhawm rau kom muaj kev kho cua sov, thiab siv cov khoom kub hauv qab no cov khoom siv hluav taws xob qis (feem ntau tsis muaj cua txias) Yog li, deformation ntxiv dag zog rau lub ntsiab yog nyob rau hauv lub reformations ntawm cov khoom siv hauv qab no (crystal tsis xws luag), muaj kev cuam tshuam ntau dua, muaj kev ntxhov siab ntau dua, muaj kev ntxhov siab ntau dua. Tom qab deformation txaus kev nyuaj siab ntawm steel yuav tsum tsis txhob sib npaug ua ntej deformation ntws kev nyuaj siab ntxiv ntxiv deformation extremental ntxiv dag zog. Kev siv ntawm kev deformation ntxiv rau kev ua kom lub zog ua kom muaj zog steel khoom, yog cov roj carbon hlau pheej kos thiab cov roj carbon ntau-rho tawm cov hlau xaim tshiab
Nrog rau kev nce qib ntawm deformation, cov khoom siv zog thiab hardness siab dua thiab siab dua, tab sis ntau nreeg, ntau dua thiab ntau dua cov kev ntsuas tsim nyog los txhim kho qhov xwm txheej. Internal induced nyob rau hauv martensitic theem hloov kho kom tawv, tab sis lub sijhawm no tsis yog los ntawm kev deformation
