| Abstract |
The flow behavior and ductility of the Aluminium alloy 5A06 was investigated in the tensile test at the elevated temperatures from 20oC to 300oC and strain rates range of 0.0006s-1 0.06s-1. The influences of strain, strain rate and temperature to elongation strain at fracture , percentage elongation , tensile strength , strain hardening exponent and strain rate sensitive exponent were researched on the basis of experimental stress-strain curves, showing 5A06 is a temperature sensitive alloy. Warm/hot hydromechanical processing of cylindrical cup deep drawing was simulated. It is demonstrated that the differential temperature mode with cool punch and heated die can enhance the forming limit significantly compared with the constant temperature mode of all tools in the same temperature. |
