چکیده مقاله:
The hydrostatic extrusion is a new method of extrusion process. The most important advantage of this method is reduction of friction and close tolerance for the coating thickness. In this study, the hydrostatic extrusion simulation of bimetallic wires has performed using of finite element method. In the following the advantages of hydrostatic extrusion compared to the direct extrusion are presented.It can be concluded that by increasing the friction coefficient between the work piece and the die, the extrusion force value also increases. Increasing the cross-section reduction when the die angle kept constant as a result of increase in die length, consequently leads to an increase in the extrusion force.Regarding to the absence of friction in the die and almost uniformly deformation and homogeneous in the hydrostatic extrusion, the product with a uniform coating thickness can be obtained as it is very important for manufacture of very high length bi-metal products.
