This research uses EBSD data of two thermo-mechanically processed medium carbon (C45EC) steel samples to simulate micromechanical deformation and damage behavior. Two with 83% 97% spheroidization degrees are subjected virtual monotonic quasi-static tensile loading. The ferrite phase is assigned already reported elastic plastic parameters, while the cementite particles properties. A phenomenolog...

The effects of starting microstructure and intercritical annealing temperature on the phase-transformation kinetics microstructural evolution a prototype Fe–0.15C–5.56Mn–1.1Si–1.89Al medium-Mn third-generation advanced high-strength steel are examined. microstructures comprise 1) an as-received cold-rolled (CR) containing significant fraction ferrite tempered martensite 2) austenitized quenched...

with careful design, mixed microstructures consisting of fine plates of upper bainitic ferrite separated by thinfilms of stable retained austenite have exhibited impressive combinations of strength and toughness in highsiliconbainitic steels. the silicon suppresses the precipitation of brittle cementite leading to an improvement intoughness. the essential principles governing the optimisation o...

To develop microstructure control concepts for ensuring the toughness of high-strength steel plates, basic research was conducted using ferrite single-phase steels with different amounts C, and effects states C were investigated along those solute N. In this study, Fe-0.017C (mass%) alloy, wherein state changed to a solid solution, intragranular cementite, intergranular used microstructural obs...
