• High Temperature Obuservation on the Behaviour of Grain-boundaries in the Vicinity of the Solid Phase Weld Interface

抄録

Grain-boundary migration on the weld interface is one of the most important factors affecting the solid phase weld properties.<BR>In this report, the behaviour of grain-boundaries in the vicinity of the weld interface during solid phase welding is pursued continuously with a high temperature microscope, and a observation method to oxidize a specimen slightly at a high temperature is compared with thermal etching method.<BR>The main results obtained in this observation are as follows;<BR>1) In case of observing grain-boundary migration with thermal etching, a sufficient understanding of the nature of thermal etching is indispensable. High temperature oxidizing method is suitable to know the location of grain-boundaries at arbitary time.<BR>2) Grain-boundary migration near the solid phase weld interface is restricted in various way by the interface. For instance, the grain-boundary that coincides with the weld interface is very hard to migrate to leave from the interface compared with the other case. In the vicinity of the weld interface, such grains as have very unstable shapes transiently are often observed; etc.<BR>3) Various processes of grain-boundary migration starting from a grain-boundary triple point formed on the weld interface are observed. (Fig. 3) At the interface without a grain-boundary triple point, the bulge type grain-boundary migration is observed.
