Cov yam ntxwv ntawm cov khoom siv hais txog cov yam ntxwv ntawm cov ntaub ntawv uas deform thiab tiv thaiv kev puas tsuaj nyob rau hauv kev ua ntawm sab nraud quab yuam
1. Lub zog
①Qhov zog ntawm cov khoom siv
②Pib qib
PeSpecific zog
2. Kev kho tsis zoo ntawm cov khoom siv
Elasticity thiab plasticity
Elasticity: Cov khoom siv deforms nyob rau hauv kev ua ntawm sab nraud quab yuam. Thaum lub zog quab yuam sab nraud raug tshem tawm, cov cuab yeej uas deformation tuaj yeem hloov kho tag nrho yog hu ua elasticity ntawm cov khoom.
Plasticity: Qhov deformation ntawm ib qho khoom hauv qab qhov kev txiav txim ntawm sab nraud quab yuam. Tom qab lub zog sab nraud tshem tawm, cov khoom tseem khaws cov duab thiab qhov loj ntawm cov khoom deformed, uas hu ua plasticity ntawm cov khoom.
RBrittleness thiab tawv
Brittleness: Cov khoom ntiag tug ntawm cov khoom siv uas tsis muaj qhov cuam tshuam loj thiab muaj kev puas tsuaj sai raws li kev ua ntawm sab nraud quab yuam. Cov ntaub ntawv nrog cov cuab yeej no hu ua cov khoom siv brittle.
Kev nruj: Cov cuab yeej ntawm ib qho khoom siv uas tuaj yeem tiv taus qhov loj deformation yam tsis muaj kev puas tsuaj sai raws li kev cuam tshuam thiab nrawm nrawm. Cov ntaub ntawv nrog cov cuab yeej no yog hu ua cov ntaub ntawv ductile.
