Research Abstract

Grain boundary is important structure factors influencing the properties of materials. Therefore, it is necessary to elucidate a role of the grain boundary. Main contents are as follows:
(a) A Calculation of the mean grain size by the intercept or the planimetric method ns carried out for a grain structure model. The grain shape and the grain diameter B were reasonably set to be the tetrakaidecabedron and to have a long-normal distribution. The equation are derived for the intercept and the plavimetric methods.
(b)Grain refinement by thermal cycling in Cu-28e alloys bas been investigated. The refinement was explained as a special case of the back notion of the front of nodules. Grain size reduced from 100 to 20 mum by the first thermal cycling.
(c)In Pure copper, two types of void formation daring high temperature tensile test were obserted. One was on a migrating grain boundary which left many fine cavities behind, and the another was on a stational grain boundary which produced larger voids followed by grain boundary failure. The influence of grain boundary structures to the cavity formation was pointed out.
(d)Void formation on grain boundaries in Cu-Zn alloy has been investigated in connection with the train boundary character. It was conducted that the strain rate affected the relationship between the propersity to void formation and
(e)Strain rate dependence of internal and effective stress is superplastic deformation were investigated using a Zn-Al eutectoid alloy. The activation energy, the grain size exponent of the flow stresses and the contribution of grain boundary sliding to the total strain have been estimated for the each deformation region.
