Taw qhia ntawm martensite
Martensite yog ib hom koom haum npe ntawm cov khoom siv hlau, uas yog cov kua roj tov cov roj carbon ntau tshaj hauv α-Fe. Nws tau xub pom nyob rau hauv ib qho tawv ntxhia hauv 1890s los ntawm German metallurgist Adolf Martens (1850-1914). Peb txheej txheem ntawm martensite feem ntau yog phaj lossis lath, tab sis nyob rau hauv kev soj ntsuam nws yog ib qho (ob- seem) nws feem ntau yog rab koob, uas yog vim li cas nws feem ntau yog vim li cas tau piav raws li rab koob. Cov qauv siv lead ua ntawm martensite yog lub hauv paus ntawm lub cev tetragonal qauv (BCT). Kev nrawm txias hauv qhov nruab nrab thiab siab cov pa roj carbon ntau tuaj yeem ua tiav cov qauv no. Lub zog siab thiab tawv tawv yog ib qho ntawm cov yam ntxwv tseem ceeb ntawm martensite hauv steel.
