Effect of Rolling on Microstructure and Wear Behavior of Hot Rolled Al6061-Beryl Composites

Article Preview

Abstract:

The present paper deals with the study of microstructure and wear characteristics of hot rolled beryl reinforced aluminium metal matrix composites (AMMCs). Al6061-beryl composites with 2, 6 and 10% of beryl were made using stir casting technique. The optical microstructure reveals the homogeneous dispersion of beryl particles in the matrix. The worn surfaces have been observed under SEM to understand the mechanism of wear. Hot rolled composites at 4500C possess higher hardness and lower specific wear rates under all loads and sliding distance studied in this investigation, when compared with cast composites.
