Kev piav qhia
Cov hlau caij nplooj ntoos hlav yog hais txog hlau vim nws lub elasticity thaum lub sijhawm quenched thiab tempered, thiab tshwj xeeb tshaj yog rau kev tsim cov caij nplooj ntoos hlav thiab cov khoom siv elastic. Cov hlau caij nplooj ntoos hlav nyob ntawm nws lub peev xwm los elastically deform, piv txwv li, hauv qhov ntau uas tau teev tseg, lub peev xwm los tiv taus qee qhov elastic deformation kom lub nra tsis tshwm sim hauv qhov deformation tas mus li tom qab lub nra raug tshem tawm.
Daim Ntawv Thov
Cov hlau tiaj tiaj caij nplooj ntoos hlav yog siv dav rau cov khoom siv hauv tsheb, kev tsim khoom tsheb, cov cuab yeej kho vajtse, kev tsim cov saw hlau thiab lwm yam kev lag luam tsim khoom siv tshuab.
