and alloy particles reinforced aluminum matrix composites were fabricated by squeeze casting with alloy particles of Ti-6 Al-l4 Vand Ni60 particles to understand difference of microstructure and mechanical properties.The experimental results show that the addition of Ti-6 Al-l4 Vparticles can improve the mechanical properties of the composites

while Ni60 particles have an opposite effect.Ti-6 Al-l4 Vparticles can realize the desirable interface bonding with the alloy matrix to be subjected to stress in the composites

while Ni60 particles can react sharply with matrix alloy to form a thick intermetallic compound layer

so the loading capacity of the composites is reduced greatly.
