Abstract : Closley packed, hexagonal epsilon-phases may be easily deformed by the extrusion method to comparatively large degrees of deformation above 0.7 to 0.8 of absolute melting temperature. The gamma-phases which are brittle at room temperature may be deformed in the hot state to extremely high degrees of deformation without destruction. In addition the temperatures of transition from the brittle into the plastic state are 0.9 to 0.97 of absolute melting temperature for the gamma-phases. Based on the results of all work and data in the literature, the authors propose the possibility of extrusion of the nickel-arsenide type and Laves phases under appropriate experimental conditions.
