Abstract
This paper presents, the hardness of a material varies depending on the composition of material, and how it is treated when processed. Here observed the changes in hardness of Cu-Cr-Zr (CRZ) alloy resulting from different process types, along with the accompanying changes in microstructure. Tests are carried out to study in detail of the Thermo-Mechanical Processing such as Cold Rolling, Hot Rolling and Tensile test on CRZ. In this paper, the hot rolling operation and cold rolling operation has been performed on small slabs of CRZ alloy. And then for prepared alloy that is hot and cold rolled alloys the microstructure has been evaluated. The hardness of these alloys is also evaluated. So based on the observations are found for each alloy a comparison study has been done. And arrived at the conclusions for each alloy that by cold working the Strength increases and ductility decreases and by hot working the strength decreases and ductility increases. And for the Tensile Test for the Solution treated samples of CRZ alloy found high strength and less ductility in comparison to the room temperature samples. The role of recrystalization on these alloys has also been explained.
