The effect of introducing the Al-Ni eutectic composition into Al-Zr-V alloys on microstructure and tensile properties

The effect that the Al-Ni eutectic composition has on the microstructure and tensile properties of Al-Zr-V alloys is discussed. It is found that the change in the alloy's solidification behavior brought about by the presence of the eutectic composition mitigates segregation of the zirconium and vanadium atoms, and by doing so it enhances the precipitation hardening characteristics of the alloy and improves its yield strength.
