Title : Effect of Manufacturing Process on Micro-structure Evolution, to Optimize Property for the Dual Phase; (HSLA) Steel & High Strength Alloy.

Abstract:

The effect of Control rolling process on microstructure evolution of Dual Phase Steel properties; Composition-Microstructure - Properties Relationships. In the present work, a micromechanical-based finite element (FE) analysis is carried out in order to investigate the mechanical properties of this type of steels, such as yield stress and tensile strength. The step forward contribution of the present study is to insert the effect of the presence of the interface of the constituting phases in the FE model. This model is then used to investigate the effect of martensite volume fraction and small-to-large particle size ratio of martensite on the deformation behavior of the DP steel. Experimental data is used to verify the created FE model. This study shows that considering the interface of the constituting phases greatly affects the numerical results on stress and strain distributions and produces more realistic findings in agreement with experiments. The results show that applying cohesive elements between two phases have reduced tensile strength, yield stress, and the amount of uniform elongation.
