Course description and aims

    This course focuses on the metallic functional materials. The definition and classification of functional materials are described, and then, functionalities, properties, characteristics, and applications of various metallic functional materials are explained systematically as classified by applications as well as by alloy systems. Moreover, topics of this course cover characteristics of lattice defects in ordered structures of intermetallic compounds, which are widely used not only as functional materials but also as functionalized structural materials, and their effects on functionalities and properties of intermetallic compounds.
    Materials, which support our daily life, industries, science and technology, can be classified into two categories, i.e., structural materials and functional materials. As the industries and technologies are highly improved, demands of functional materials increase drastically while required functionalities of materials are widely diversified according to the changes of needs in applications. Students learn properties and roles of metallic functional materials in this course, and acquire their knowledge and skills which are required to design, to develop, to fabricate and to apply functional materials in the science and engineering field.

Student learning outcomes

By the end of this course, students will be able to:
1) Explain that functions and properties of materials originate from crystal structures, lattice defects, phase boundaries, and microstructures.
2) Derive the interaction parameter for binary alloys and explain ideal solution, phase separation, ordered phase formation. Explain anti-phase boundaries formation along with the ordering and how to evaluate short and long range ordered parameters.
3) Explain phase stability of intermetallic compounds as characteristics of phase diagrams regarding the stoichiometric compositions, and explain various point defects introduced in ordered structures at off-stoichiometric compositions of intermetallic compounds.
4) Explain super lattice dislocations introduced in ordered structure of intermetallic compounds as compared with ordinary dislocations of random solid solution phases.
5) Explain the characteristics and applications of soft magnetic materials and hard magnetic materials based on the hysteresis of their magnetization curves.
6) Explain fundamental material designs and applications of energy conversion materials, such as heat resistant alloys, solar cells, fuel cells, and thermoelectric materials
7) Explain characteristics and applications of currently developing Cu alloys.
8) Explain characteristics and applications of functional Ti alloys.
9) Explain characteristics and applications of shape memory alloys and super-elastic alloys.
10) Explain classification and characteristics of biomedical metallic materials.

Class flow

Exercise problems are assigned to students at the beginning of each class, and group discussion is held during the class according to topics to be learned. This course consists of the first half and the second half, and understanding level check-up test is scheduled as the summary at the end of each half. Students should read the course schedule to check topics covered on that day, and preparation and review are required.
