Internal Friction, Electric Resistance and Shape Change in Cu-Zn Alloy during Martensitic Transformation

The internal friction, electric resistance, shape change, frequency and temperature in Cu-Zn alloy were measured simultaneously during phase transformation. The results show that the change of those quantities were exhibited certain correlation. The change of electric resistance in Cu-Zn alloy during phase transformation was calculated and the calculation result is well consists with the experimental curve.
