A Study on Enhancement of Mechanical Properties in Particulate Reinforced MMC (Metal Matrix Composites)

In this paper we have discussed about enhancement of mechanical properties of MMC. Metal Matrix Composites are made out of a metallic matrix (aluminum, magnesium, iron, cobalt, copper) and a dispersed ceramic (oxides, carbides) or metallic (lead, tungsten, molybdenum) phase. This paper deals with the detailed experimental strategy carried out in the current investigation. As referenced in the past chapters the work was aimed at creating chilled aluminum alloy-Nano ZrO2 particulate MMC for automotive, defense and other structural applications. In this manner, the alloy chose was LM 13 which is widely utilized in the automobile industries for the manufacture of cylinder and chamber sleeves. Further, the investigation was carried out at the chill end of castings, which was done to study the impact of the chill on the microstructure, mechanical, tribological, thermal behavior of the composites.
