This course gives an introduction to the fundamental theories of physical metallurgy. Students will master the relationship and change rules among the composition, structure and properties of metals and alloys. Master the knowledge of thermodynamics, diffusion, interface, metal solidification, diffusional transformation and diffusionless transformation in metal materials. Understand the manufacturing and heat treatment methods of common structural materials such as steel, aluminium alloys, copper alloys and titanium alloys. Meanwhile understand the research progress of some new metal materials such as metallic glass, shape memory alloys and high entropy alloys. After finishing the course, students are expected to use the learned theories to briefly analyse some typical practical engineering problems.
