Synthesis and Forming Behavior of In Situ AA 7075 - TiC Composites

Article Preview

Abstract:

The forming behavior of a particulate reinforced AA 7075-TiC composite produced by in-situ stir casting process was investigated with cold upsetting test using graphite as lubricant. The prepared composites containing 0%, 4% and 8% of TiC reinforcement was completely investigated under tri-axial stress state condition. The various stress parameters were evaluated for all the above said composites and its variation with respect to axial strain was plotted, studied and discussed. Microstructural characterization of the composites was also done to study the distribution of the reinforcement in the metal matrix composite.
