Microstructural Changes During Hot Rolling of Zn-Al Eutectoid Alloy with 2% Cu

Abstract The influence of the rolling temperature on the final microstructure and hardness of the rolled Zn-Al eutectoid alloy modified with 2% Cu, was investigated. The alloy rolled above the eutectoid temperature is harder than the alloy rolled below the eutectoid temperature. The final phases of the alloy rolled at 300°C are α, η, and e. In the alloy rolled below the eutectoid temperature the final phases are α, η, and τ'.
