Abstract :

In this paper, 1.7225 steel subjected to severe plastic deformation by using a multi-directional forging method, and mechanical properties such as ultimate tensile strength, yield strength, hardness and, vibration properties were investigated. The use of SPD ( severe plastic deformation ) for changing the size of metals grain to enhance the mechanical properties of the metals were examined. The 1.7225 steel is used for machine tools with appropriate mechanical properties as a tool holder. First Evaluation of load needed for plastic deformation was conducted by using finite elements computer software. By using the results of the software first guess for applied load and stresses on the die for successful results were known. The results of this study showed that the yield and ultimate tensile strength increased 441Mpa and 540Mpa and hardness increased 18HRC. After 2 passes of severe plastic deformation, mechanical vibrations characteristics result no significance change in damping properties.
