Notes:
Microstructure and mechanical properties of 20% Al-Cu-Cr/Al composites synthesizedby hot-pressing technique after annealing, quenching and aging was studied by means of X-raydiffractometer (XRD), scanning electron microscopy (SEM) and transmission electron microscopy(TEM) and uniaxial compressive test. Microstructure of Al-Cu-Cr particles in the composites afterhot-pressing is mainly consist of icosahedral quasicrystals and which transformed into decagonalquasicrystals 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 thecomposites are improved by age-hardening
