This study employs commercial DEFORM™ 3D software to simulate the plastic deformation behavior of titanium and brass alloy billets in the hot extrusion forming of finned CPU heat sink. The simulations consider the respective effects of the extrusion material, the friction factor, the processing temperature and the die dimensions on the axial load, the effective strain, the effective stress, the material damage, the velocity distribution and the radius of curvature of the extruded product. A CPU heat sink extrusion mold is fabricated in plastic and used to produce a clay heat sink. The simulation results confirm the suitability of the DEFORM™ 3D software for forming of titanium alloy and brass alloy using extrusion process of heat sink for CPU modeling the plastic deformation of titanium and brass alloy billets in the extrusion of CPU heat sinks.
