Popis: |
To synthesize Al composite with high strength at elevated temperature, high modulus and thermal stability, ZrB2, Al3BC and Al2O3 particles have been chosen as reinforcements simultaneously. A (9.2 wt.% ZrB2 + 5.6 wt.% Al3BC + 5.5 wt.% Al2O3)/Al composite has been prepared, and the in-situ synthesized particles are nano-sized. Mechanical property tests reveal that the nanoparticles exhibit a remarkable synergistic enhancement effect. The elasticity modulus of the composite is 89 GPa, and the ultimate tensile strengths at 25 °C and 350 °C can be as high as 371 MPa and 154 MPa, respectively. |
