| Research Abstract |
A new (precise marking method) method which allows the quantitative measurement of the degree of inhomogeneity of plastic deformation was proposed with the aim to improve the mechanical properties of structural material such as high tensile strength steel. Executing the establishment of this new technique, the quantitative measurement of local deformation behavior of materials was achieved. In particular, this method is effective to examine the plastic deformation behavior of the multi-phase materials which consists of soft phase and hard phase. By systematic series of the studies, it is clarified that the characteristic of strain distribution of soft phase and the contribution of hard phase to mechanical properties of the materials.
