Temperature and strain rate effect on flow stress of al2075/bottom ash composite

Abstract

This study focused to determine the flow stress of Al 2075 composites with bottom ash reinforcement. Metal forming process is very important in an industry, materials can be plastic deformed requires several parameters of the forming process, such as the material flow stress. Temperature and strain rate affect the flow stress material. In this paper the tensile test carried out at 350°C, 400°C and 450°C and the strain rate varied 1 mm.s−1, 10−1 mm.s−1 and 10−2 mm.s−1. Tensile test showed that the highest flow stress is obtained at 350°C and a draw rate of 1 mm.s−1, the higher the temperature will decrease the flow stress, while the faster the strain rate increased the material flow stress.
