EXPERIMENTAL INVESTIGATION OF CREEP BEHAVIOUR OF ALUMINIUM ALLOY (LM25) AND ZIRCONIUM DI-OXIDE (ZRO2) PARTICULATE MMC

Aluminium metal matrix composites are one of the new materials used for various applications due to their less cost and light weight. Creep is the tendency of solid material to slowly move or deform permanently under the influence of stresses when subjected to high temperatures for long duration of time. So creep is one of the major considerations while analyzing the materials which are used for high temperature for long durations. Creep analysis of composite material has a wide scope of research. In this paper, an Aluminum composite material is produced by mixing high strength low weight material with zirconium di-oxide for different proportions (0%, 3%, 6%, and 9%) by using stir casting technique. In this paper experimental tests were carried out to determine the creep strength for different proportions (0%, 3%, 6%,9%) of Zirconium-di-oxide with LM25 by creep testing machine. SEM and microstructure analysis was also done to see the distribution and presence of ZrO2 particles in aluminium alloy.
