| Abstract Scope |
Friction extrusion is a solid phase processing that produces metal and alloy wires with refined microstructure and improved mechanical properties. Like friction stir welding and processing, plastic deformation is produced near the interface between the rotating die and the material being extruded. It is believed that tool surface features may play a critical role in the details of heat generation and material flow. However, the effect of die face feature, like scrolls in comparison to flat featureless dies, has not been systematically studied.
In this research, scroll dies and flat dies are employed in rate-controlled friction extrusion. A marker insert technique was used to visualize material flow and calculate the strain in wire. The differences in extrusion force, temperature, torque, power, and strain in the wire are compared and discussed relative to the varied die geometry. Smoothed particle hydrodynamics model was applied to simulate the process and explain results. |
