摘要：

Compressive and tensile tests were performed by using both single and polycrystal specimens of an intermetallic compound Ni//3Al which was generally believed to be brittle. In particular, the ductility was examined by comparing the elongation of specimens through the observation of fracture surfaces. Polycrystal specimens homogenized after casting do not show any elongation by tension at every temperature, and the fractured surfaces exhibit an intergranular fracture mode. Single crystal specimens show about 100% elongation at and below room temperature.
