Structure and Properties of Materials for Mechanical Engineering/ Exercise 1

The microscopic characteristics expressed by metallic materials are governed by the microscopic structure of metals. In particular, hydrogen atoms with the smallest atomic radius easily diffusively intrude into metallic materials. While a positive effect from hydrogen can be gained from its use in hydrogen storing alloys, the phenomenon of hydrogen brittleness can be raised as one of its negative effects. This course will center around the major theme of “materials and hydrogen,” investigate the microscopic structural changes of metallic crystals through hydrogen injection targeting mainly metals and intermetallic compounds, and investigate the onset mechanism of mechanical properties such as hydrogen brittleness and environmental embrittlement which are induced in metallic materials. As well, students will conduct experiments and numerical simulations etc. to improve hydrogen absorption and desorption properties in hydrogen storing alloys. The following are some main themes:
1. Microscopic condition of solid solution hydrogen and trapped hydrogen
2. Hydrogen diffusion, hydrogen discharge
3. Crystal structural defects (mainly dislocation) and hydrogen
4. Hydrogen storing alloys and hydrogen storing materials
5. Hydrogen susceptibility and hydrogen brittleness of advanced materials

1. To deepen professional knowledge on materials engineering.
2. To understand a sequence to proceed engineering research.
3. To understand how to search suitable literature related to your study.
4. To read published literature and to understand English technical terms.

English

Classes and related research works are based on discussion with students. After selecting a research topic, students will work for research with a consultation from the instructor. Presentation on published literature, research progress reports and submitted research papers are occasionally requested by the instructor.

Evaluation will be based on students' performance on presentation on published literature, research progress reports and submission of research papers. Presentation at a domestic or an international conference once a year is highly encouraged.

recent published literature. handouts will be distributed.
