[Materials] Microstructures and related mechanical properties of metallic materials can be varied with processing conditions even when their chemical compositions are exactly the same. These characteristics of metallic alloys can be understood in terms of phase equilibrium (phase diagram), kinetics of phase transformations (continuous cooling transformation curve, time temperature transformation curve), and dislocation theory (strengthening mechanism). Students will understand the relationship among processing, microstructures and mechanical properties through the experiments associated with ferrous and non-ferrous alloys, In the end of this course, students are requested to design evaluation and testing methods for a given problem by group, and to present the results and discussions in English at the final presentation.
