Abstract
The effect of iron on the mechanical properties and microstructures of Cu-11.2 weight % Al alloy in the isothermal transformation was investigated by tensile test and metallographic techniques. This investigation results showed that the addition of two weight % iron in Cu-11.2 weight % Al alloy with proper heat treatments produced the fine microstructures and the fine precipitate particles in the α phase and these microstructures had pronounced effects on the ultimate tensile strength. The ultimate tensile strength of 110,000 psi was obtained at room temperature.
