 In this study, we investigated the CRETE properties of 60 Zambian Quacha alloy and a 60 Zambian Quacha per CCP composite at 200 degrees Celsius and 250 degrees Celsius in the 10 to 80 MPa stress range after the Kobo extrusion and precipitation hardening process. We found that the true stress exponent was in a range of 1.6 to 2.3 for both the unreinforced alloy and the composite. Additionally, the apparent activation energy of the unreinforced alloy was found to be in the range of 80.91 to 88.09 kilojoules per mole while that of the composite was found to be in the range of 47.15 to 81.60 kilojoules per mole. This indicated that the grain boundary sliding, GBS, mechanism was present in both materials. Furthermore, an investigation of CREP microstructures using an optical microscope and scanning electron microscope, SEM, revealed that at 200 degrees Celsius, the predominant strengthening mechanisms at low stresses were the formation of twin, double twin, and.
