電子顕微鏡観察下における微小試験片の単軸引張試験システムの開発

We developed a micro-scale tensile fatigue test system, which can test specimens fabricated from bulk materials. In this system, a probe is attached to a micro-manipulator and the micro-manipulator enables accurate initial positioning and applying tensile stress. In this paper, we present the system and the result of tensile tests on the specimens which are made of coarse-grained magnesium alloy, AZ31. The tensile tests suggest that the system can apply accurate tensile stress to the micro-scale specimens, the tensile strength of micro-scale structures is much stronger than that of bulk materials and the tensile strength is dependent on the crystal orientations.
