Kev laus yog ib qho tseem ceeb cov kauj ruam uas ua kom cov ntaub ntawv nyob rau hauv lub alloy tsis rov qab mus rau lawv tus qub configuration tom qab ib lub sij hawm. Kev laus yog ua nyob rau hauv kev tswj tej yam kev mob kom lub resultant grain qauv yuav tsim ib tug ntau dua tensile lub zog nyob rau hauv lub hlau tshaj nyob rau hauv nws lub xeev qub.

Yog li ntawd, dab tsi yog strain aging ntawm steel?

Thaum twg hlau tau raug strained (deformed plastically) thiab tom qab ntawd tso cai rau lub hnub nyoog, nws tau raug ua raws li lub npe hu ua lim kev laus . Nws paub tias lim kev laus yog nrog los ntawm kev txo qis ntawm pob txha toughness, uas feem ntau tshwm sim los ntawm qhov nce ntawm qhov kub thiab txias (BTT).

Ib tug kuj yuav nug, dab tsi yog cov khoom aging? Gradual txheej txheem nyob rau hauv uas cov khoom ntawm a khoom , qauv, los yog lub cev, hloov (kom zoo dua los yog phem dua), dhau sij hawm los yog nrog kev siv, vim yog cov tshuaj lom neeg, tshuaj lom neeg, los yog lub cev ua haujlwm.

Cov hlau puas nyuaj nrog lub hnub nyoog?

Txij li thaum Hnub nyoog hlau , metallurgists muaj paub tias hlau xws li steel ua kom muaj zog thiab nyuaj dua qhov ntau koj ntaus (los yog ntaus) rau lawv. “Thaum koj ntaus rau hlau , dislocations ntau zoo li vwm, Bulatov hais. “Qhov hlau tau muaj zog , tab sis peb tsis paub meej tias lub zog ntawd tuaj txog li cas.
