In the present investigation, aluminum alloy (LM 13)-nano-ZrO2 metal matrix composites were manufactured by stir casting technique followed by the hot extrusion process. The nano ZrO2 particulates addiction varies from 2 to 10wt% in steps of 2% in the composite. The metallographic and SEM tests were conducted for confirmation of the presence of ZrO2 particulates in the LM 13 alloy and to know the distribution of the ZrO2 particulates in the Lm 13 alloy. The micro hardness, tensile test, and compression test were conducted on the nano metal matrix composites. The result reveals that the mechanical properties were improved in the nano metal matrix compared to the alloy. The heat treatment and the extrusion process have very good influence on improvement of the mechanical properties in the nano metal matrix compared to the alloy.
