摘要：

In this experimental investigation aluminium hybrid metal matrix composites (MMCs) is fabricated through stir casting process by varying the Zirconium oxide (ZrO2) (2%, 4% and 6%) and keeping the percentage of graphite (C) as constant (3%). In this paper effect of weight percentage of reinforcement were investigated. Microstructure, microhardness and ultimate tensile strength were estimated for the different weight percentage of reinforcements. Microstrucutre reveals that the distribution of the reinforcement and non evident of the clustering of the reinforcements in the aluminium hybrid MMCs was due to the stirring effect. Microhardness records its highest value of 95.4 VHN for 6% of ZrO2 and minimum value of 76.8 VHN for 2% of ZrO2 and 3% of C. Higher tensile strength of 149 MPa is observed for the 6% of ZrO2 and 3% of C and lower tensile strength of 134 MPa for the 2% of ZrO2 and 3% of C. (C) 2019 Elsevier Ltd. All rights reserved.
