Effect of Temperature on the Evolution of the Dislocation Structure of Ni Single Crystals

Resumo

The dislocation structures and stress–strain curves of Ni single crystals with a [100] compression axis are studied at temperatures of 293 and 673 K. The dislocation structures for both temperatures are shown to arise in the sequence cellular, band, and fragmentary. A rise in temperature has no effect on the type of substructures that are observed in strained Ni single crystals, despite the difference between their parameters.
