Abstract Based on the point of view of mechanics,the cracking analysis ofmicrostructure in dual phase materials was analyzed,the concept of equal strengtth designand its equation were introduced,and the critical length(l_0) of martensite phase inF(ferrite)-M(marte

Key words: microstructure dual-phase steel cracking analysis equal strength design critical length
