Microstructure and properties of pure titanium processed by equal-channel angular pressing at room temperature
Microstructure and properties of pure titanium processed by equal-channel angular pressing at room temperature
Experiments show that commercial purity titanium may be processed by equal-channel angular pressing at room temperature by increasing the channel angle within the die and using a relatively slow ram speed. The microstructure of the pressed material contains shear bands and deformation twins as found in titanium pressed at significantly higher temperatures. The material also exhibits improvements in the yield stress, ultimate strength and microhardness that are slightly greater than the improvements attained after pressing at higher temperatures.

Abstract
Experiments show that commercial purity titanium may be processed by equal-channel angular pressing at room temperature by increasing the channel angle within the die and using a relatively slow ram speed. The microstructure of the pressed material contains shear bands and deformation twins as found in titanium pressed at significantly higher temperatures. The material also exhibits improvements in the yield stress, ultimate strength and microhardness that are slightly greater than the improvements attained after pressing at higher temperatures.
