Extract

The microstructures and mechanical properties of Ni-Al system intermetallic compounds used as heat resisting materials have been investigated by many researchers[l,2], but there are few studies applying X-ray stress measurement to these materials[3]. Two problems make it difficult: One is the comparatively coarse grain size, the other is the strong preferred orientation along the direction of the solidification. Therefore, it become possible to evaluate mechanical behavior in these materials, if we can measure the residual stresses correctlv by X-rays.

In this paper, Ni-25mol%AI(Ni3Al) made by the arc-melting method was employed. It consists of comparatively coarse grains and has strong preferred orientation along the direction of the solidification.
