| Research Abstract |
The mechanical properties of metallic materials are dominated by their microstructure, including grain boundaries, and precipitates. Therefore, to develop materials with superior mechanical properties, it is important to examine the mechanical properties of each microstructural constituent. We have developed a testing machine that enables the measurement of mechanical properties of microsized materials. The mechanical properties of microsized specimens prepared from microstructural constituents of multiphase alloys, including lamellar structured TiAl alloys, Mg-Zn-Y alloys and steels have been measured. This testing method is useful for multiscale material design.
