High-pressure alloy yeeb nkab deformation reinforcing yog siv txoj kev deformation ntawm steel reinforcement.Kuj tseem hu ua strain hardening lossis ua haujlwm hardening.Lub zog ntawm cov khoom ntawm macro (los yog tag nrho) muaj peev xwm tiv taus deformation (los yog txaus siab).Hardness yog lub peev xwm ntawm cov khoom siv los tiv thaiv cov yas deformation hauv zos (txawm tias micro-hardness, Vickers hardness, Rockwell hardness lossis Brinell hardness).Ob leeg muaj kev sib raug zoo sib xws hauv ntau qhov xwm txheej.Lub zog ntawm cov khoom, qhov ntau dua qhov kev tiv thaiv ntawm cov yas deformation, qhov hardness ntau dua.Piv txwv li, qhov siab dua qhov hardness ntawm cov khoom, cov khoom yuav yog vim muaj zog brittleness, nws lub zog tsis yog tag nrho reflected nyob rau hauv xws li lub zog Performance index tus nqi yog tsis siab.

Rau kev kho cua sov ntev dua, thiab kev siv cov khoom siv nyob rau hauv qhov kub thiab txias hauv qab lub recrystallization kub ntawm high-pressure alloy yeeb nkab steel yeeb nkab khoom (xws li low-carbon low-alloy steel), feem ntau siv txias (txias deformation) yog li. uas los ntawm txoj kev deformation ntxiv dag zog los txhim kho lub zog.Yog li, deformation strengthening essence yog nyob rau hauv lub recrystallization kub ntawm cov khoom nyob rau hauv cov nram qab no txias deformation, nrog rau cov degree ntawm deformation (strain) yog nce, uas ua rau ib tug siab ceev ntawm dislocations (crystal defects), lub siab dua lub dislocation ceev nyob rau hauv lub crystal. , qhov ntau dua qhov kev txhim kho, uas yog qhov kev ntxhov siab ntau dua.Tom qab deformation flow stress ntawm steel yuav tsum tsis txhob sib npaug ua ntej deformation flow stress ntxiv rau incremental deformation ntxiv dag zog txaus siab.Kev siv cov deformation ntxiv dag zog kom ua tiav cov khoom muaj zog steel, feem ntau yog cov high-carbon steel txias-drawn steel hlau thiab qis carbon low-alloy duplex steel txias-draw steel hlau.

Nrog rau kev nce qib ntawm deformation, cov khoom siv zog thiab hardness siab dua thiab siab dua, tab sis nws cov ductility thiab toughness feem ntau tau qis dua thiab qis dua, ntau dua thiab nkig, uas yuav tsum tau ua kom nruj los ntsuas qhov tsim nyog los txhim kho qhov xwm txheej.Sab hauv induced nyob rau hauv martensitic theem transformation theem txias rau hardening, nws lub cev essence, nws kuj belongs rau deformation ntxiv dag zog rau, tab sis lub sij hawm no tsis yog los ntawm sab nraud deformation, tab sis cov txheej txheem ntawm martensitic transformation los ntawm crystal High-density qhov chaw nws tus kheej shear generated los ntawm yuam kev.
