| Research Abstract |
Experimental analyses were performed to elucidate the effect of gaseous environment on the strength against crack initiation from interface free-edges in micro-scale components. The micro-components containing interfaces were fabricated with a focused ion beam technique. A specimen holder with a precise loading apparatus was operated in a high-voltage transmission electron microscope equipped with an environmental cell. The in-situ observation of interfacial fracture process, as well as the measurement of critical load at fracture, was successfully conducted for the first time in a gaseous environment. However, a systematic study needs to be further implemented to clarify the mechanism of environmental effect.
