Effect of microstructure on mechanical properties in dual phase steel

복합조직강의 기계적 특성에 미치는 미시조직인자의 영향

A study has been made to clarify the microstructural effect on static tensile properties of the dual phase steel, in which the martensitic phase encapsulated islands of ferritic phase. The main results are as follows: Yield strength is associated with the degree of plastic constraint factor and tensile strength increases with increasing of strain hardening exponent. Also, the variation of ductility is dependent upon the amount of micro-brittle facets.
