| Abstract Scope |
Pasing electric current through the metal during forming has shown to change the behavior of some metals whereas, it does not affect the others. The current is applied to the AZ31 alloy through copper fixtures, which serve as heat-sinks due to their high thermal conductivity, leading to a non-uniform temperature distribution. This temperature gradient can be leveraged to extract creep data at multiple temperatures under constant stress using DIC. This creep test is compared with conventional creep test to check the effect of current on material. Stress exponent n and activation energy for creep is obtained by performing test in temperature range of 150°C-200°C. It has been found that the steady state creep rate, n and Q is similar for both types of test. As in EAD test, we can get creep data from a range of temperature, it has potential to be used as high through-put creep testing method. |
