- Abstract
The submitted paper aimed to investigate the hot deformation behavior of CuCr0.6 alloy. Nil strength temperature of 1349 K and nil ductility temperature of 1313 K have been experimentally determined. Formability is monotonously increased with the decrease of forming temperature in the temperature range from 923 K to approx. 1273 K. The flow stress curves were obtained in the forming temperature interval of 923-1223 K and at a strain rate of 0.1-10 s-1. After their analysis, the hot deformation activation energy of 340 kJ mol-1 was calculated for peak stress and 393 kJ mol-1 for steady state. This proves that the value of the activation energy depends upon a strain size.
