Evaluation and optimization of metal matrix composite strip produced by single roll continuous strip casting method

It has been observed that size and distribution of reinforcing particle in the matrix affects the mechanical properties. Smaller size particles improve the strength and hardness of the composite. But in case of coarse particles (53-75 μm), distribution and recovery is found to be better than that of smaller size particles (<25 μm). Better distribution of particles and increase in strength was also observed at higher rpm of the caster drum. Composite strips have shown better strength at elevated temperature (<250 °C) than the matrix alloy. Improvement in ductility of composites was also noted at elevated temperature.
