Abstract In situ TiB2/Al-4.5Cu composites with different TiB2 particle amounts were fabricated by the salt-metal reaction technique. The effects of in situ TiB2 on the microstructure and mechanical properties of Al-4.5Cu alloy were studied in this paper. The results showed that in situ TiB2 particles had significant effect on refining grain size and improving mechanical properties of as-cast Al-4.5Cu alloy. With the amounts of TiB2 particles increasing, the yield strength and ultimate tensile strength were improved, while the elongation reduced. The strengthening mechanisms of the in situ particle-reinforcing Al matrix composites were discussed, and the yield strength was predicted accurately by accounting for the three strengthening mechanisms and particle distribution.

Microstructure and mechanical properties of 20% Al-Cu-Cr/Al composites synthesized by hot-pressing technique after annealing, quenching and aging was studied by means of X-ray diffractometer (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) and uniaxial compressive test. Microstructure of Al-Cu-Cr particles in the composites after hot-pressing is mainly consist of icosahedral quasicrystals and which transformed into decagonal quasicrystals after annealing. Microstructure of matrix in the composites after hot-pressing, annealing, quenching and aging is pure Al, Al + Al2Cu, supersaturated solid solution Al and Al + Al-Cu transition phases respectively. Hardness, fracture strength and the Young’s modulus of the composites are improved by age-hardening.
