Abstract
A transmission electron microscopy investigation of deformed Ni3(Al, Ti) single crystals has shown that, over the temperature range − 107°C to 917°C, there exist five distinct regions, each having a characteristic dislocation structure. No primary cube slip was observed at temperatures below approximately 450°C, the temperature of the peak proof stress. This observation makes untenable any theory which attributes the anomalous, positive dependence of the proof stress to an interaction between primary cube and octahedral slip.Keywords
