Course description and aims

This course focuses on the relationships among crystal structure (phase), defect structures (dislocation) and properties of metals in the first half, since the physical properties of metals and alloys are determined by the crystal structure and microstructures. Emphasis is placed on the thermodynamics of phase transformation and phase diagram to learn basics of the relationship between phase diagram and microstructure. The last half of this course covers the materials design of various functional materials. Practical exercises are set to improve understanding throughout this course.

Student learning outcomes

At the end of this course, students will be able to:
1) Have understanding of basic principles to control phase and microstructure that determine physical properties of metallic materials
2) Have understanding of basics of phase equilibrium
3) Have understanding of basic concepts to control properties of various functional materials

In the first half of this course, phase equilibrium, phase diagram, crystal structure, defect structure, mechanical and functional properties of multicomponent system are covered to understand relationships among phase stability, phase and properties of metals and alloys. The last half of this course covers the practical alloy design of various functional materials in terms of controlling phase equilibrium and microstructure.

Keywords
