Outline of Final Research Achievements

We developed a procedure for identification of material parameters in crystal plasticity analysis for dual-phase structural materials. In the procedure, first, tensile loading tests for micro-scale specimens are performed to identify possible deformation modes, which are implemented into the crystal plasticity method. Subsequently, material parameters are identified by fitting to lattice strain development which is obtained by in-situ neutron diffraction by TAKUMI facility of MLF in J-PARC. The procedure was applied to two-phase magnesium alloys consisted of α-Mg phase and LPSO phase.

Academic Significance and Societal Importance of the Research Achievements

本研究で構築した手法は,結晶塑性解析の信頼性向上に貢献するものである.近年,結晶塑性解析は固体力学と材料科学の両分野で普及が著しいことから,本研究の成果が両分野の基礎研究をさらに推進し得るという点で高い学術的意義を持つ.また,結晶塑性解析は構造材料の材料設計やプロセス設計への応用も期待されており,工学的応用を通して社会に貢献し得ることから,社会的意義のある研究成果と言える.
