In steels the dependence of ambient temperature microstructure and mechanical properties on solidification rate is not well reported. In this work we investigate the microstructure and hardness evolution for a low C low Mn NbTi-microalloyed steel solidified in the cooling rate range of 1-50 Cs-1. The maximum strength was obtained at the intermediate solidification rate of 30 Cs-1. This result h...

Systematic integration of atomistic simulations with phase-field modeling is presented for quantitative predictions cellular growth and solute trapping during solidification alloys velocities relevant to additive manufacturing. For parametrization the model, molecular dynamics are utilized as an alternative complex experiments obtain anisotropic crystal-melt interface free energy, kinetic coeff...
