Abstract

Optical metallography and transmission diffraction electron microscopy are used to show that the micro- and mesostructure of cast and pressure-synthesized intermetallic Ni3Al differ considerably. Four types of grains of the major Ni3Al phase are revealed in the synthesized intermetallide that differ in their domain and dislocation structure. These are single- and polydomain grains with or without dislocations.
