The Deformation of brass and bronze materials at high temperatures

In this research, copper alloys brass and bronze have been exposed by a compression test at 400 °C and 600 °C temperatures with constant deformation rates. Depending on the deformation rates and the constant testing temperatures, at defined constant deformation percentages, the flow and the ultimate compression strengths of materials are determined. The appropriate design characteristics for plastic deformation have been obtained. Depending on the constant deformation rates, the microstructure variations at warm and high deformation temperatures have been examined. The influences of deformation rates and temperatures on the microstructure alterations and compression stresses have been studied. The parameters that define the strain-stress relation of the materials have been provided along with essential data for users in order for them to benefit from in the field of design and in forming a constitutive equation for further research.
