The recovery of tensile Properties of CuCrZr Alloy after hot Isostatic Pressing
The effects of hot isostatic pressing on the tensile and thermal properties of precipitation hardened CuCrZr-alloy and their possible recovery by a subsequent ageing treatment have been investigated. For this purpose hot isostatic pressing was simulated by solution annealing treatments finished with cooling rates between 0.03Ks(-1) and 1.5Ks(-1). The experiments revealed that a successful recovery of the desired tensile strength is only achievable if the hot isostatic pressing is finished with a cooling rate of at least 1Ks(-1). In combination of scanning and transmission electron microscopy the reason was found in the changes of a bimodal precipitation distribution on a microscopic and mesoscopic length scale.
