Compression-torsion forming experiment and die design |
| |
| Abstract: | The compression-torsion forming technology has been used in preparing ultra-fine grain material. Torque and compression are applied to the billet simultaneously in the cross section direction and the height direction, thus large deformation would happen in the billet and ultra-fine grain material is then formed. A compression-torsion forming die was designed for experiment. The die structure, working principle were introduced. The die has been used in practice, which has the advantages of reliable, widely applicable, and low cost. |
