| Research Abstract |
The mechanical properties of materials are dominated by their microstructure, includinggrain boundaries, and precipitates. It is, therefore, important to examine the mechanicalproperties and deformation behavior of each microstructural constituent to develop materials with superior mechanical properties,. However , the measurement of mechanicalproperties and observation of the deformation behavior of each microstructural constituentare difficult because the size of microconstituents is on the order of microns. We have developed a testing machine that enables the measurement of mechanical properties andin-situ observation of deformation behavior of microsized materials. This testing machineis equipped with a white-light interferometer that can measure with a resolution of 0.1 nmthe surface profile of a microsized specimen during its deformation. We have measured themechanical properties and observed the deformation behavior of microsized specimensprepared from microstructural constituents of martensitic steel and Mg-Zn-Y alloy
