Structure, physical and mechanical properties, and fracture of hot consolidate Al–Ti, Al–Ti–Si powder composites

Resumo

Structural examinations and strength tests of powder composites are carried out. The powder composites are produced by hot consolidation of aluminum, titanium, and silicon powder blends. The temperature and deformation modes of the hot consolidation to get the maximum bending strength and plasticity are determined. It is shown that the bending strength and plasticity of the hot compacted powder composites depend basically on the mechanical properties of a metal matrix being formed by joining of the adjacent aluminum particles during hot deformation processing.
