This course provides a comprehensive overview of critical microstructural mechanisms in metals. It integrates theory and simulation to examine dislocations, stacking fault energy, nucleation and growth, cold working effects, and annealing-related recovery. Learners will engage with interactive content, visual simulations, and assessment activities designed to reinforce foundational and advanced concepts in metal deformation and transformation. Targeted at students and professionals in materials engineering, metallurgy, and applied physics.
