Research Progress in Tungsten and Its Alloy by Plastic Processing

Abstract:

This paper briefly introduce the methods of improving the material properties of tungsten and its alloy. Including the application status of major plastic processing methods (rolling, swaging, extrusion and severe plastic deformation methods), and the effect of these technologies on the properties (microstructure, mechanical property, recrystallization temperature and DBTT) have been summarized. Based on the analysis about powder mechanism of consolidation, a direct solidifying of tungsten powder via severe plastic deformation methods is researched.
