| Popis: | Commercial purity titanium cylindrical samples with a diameter of 11.5 mm and a length of 24 mm were processed under the condition of 773 K, 2.4 mm/s punch, 1-4 equal channel angular pressing passes by a new severe plastic deformation process called the rotary-die equal channel angular pressing (RD-ECAP) process. Using this process, it was possible to conduct an ECAP process of 2 passes or over without sample removal, and the temperature of the commercial purity titanium could be controlled. Following the RD-ECAP process, the commercial purity titanium contained no cracks, and fine-grained microstructures were observed in the samples. |
