| Outline of Final Research Achievements |
We developed a micro-scale tensile fatigue test system, which allows testing micro specimens fabricated from bulk materials. The system consists of a probe attached to a micro-manipulator, a micro-manipulator for accurate initial positioning and applying tensile stress, and a scanning electron microscope for observation. This paper reports the design of the system and the result of tensile tests and tensile fatigue tests on the specimens which are made of coarse-grained magnesium alloy. The tensile tests suggests that the system can apply accurate tensile stress to the micro specimens and its tensile strength is much larger than that of bulk materials. In addition the tensile fatigue test indicates that the system can apply intended cyclic tensile stress.
