ملخص المقالة :
There are several parameters that have significant influence in metal forming process. One of the most important of them is friction coefficient. Friction can change the pattern of metal flow and the force needed for deformation. It is necessary to determine the friction coefficient to study the effect of friction on metal forming process. This study is concerned with numerical and experimental studies on Ti-6Al-4V alloy by using T-shape friction test at elevated temperatures. B means of the FE simulations and experimental tests have been studied effects of parameters temperature, ram velocities, and die edge radius and friction conditions in T-shape friction test. Based on numerical results and experiment, by increasing the die speed, increasing the radius of edges, or reducing the temperature of experiment, sensitivity of friction in T-shape experiment is increased. At the end, flux curve of compression experiments, friction coefficient of T-shape experiment, and simulation in Deformer software were at a good agreement
