Plastic flow and dislocation structures in tantalum carbide: Deformation at low and intermediate homologous temperatures

Dislocation structures and plastic flow in TaC 0.99 have been studied in material deformed by microindentation at 20°C, and in specimens crept at temperatures between 0.37 and 0.43 T m (1300–1500°C). Extensive local plastic deformation occurred during indentation, accomplished mainly by the motion o...
