Hybrid metal matrix composites (HMMC) have gained importance in industrial applications owing to their tailorable properties. The properties of HMMC are influenced by the casting process parameters. In this work, AA6061-reinforced Al2O3/SiC HMMC were fabricated by squeeze casting technique. The effect of four levels and four input parameters are squeeze pressure, pressure holding time, die material, and melt temperature is investigated. L16 orthogonal array was selected to perform the experiments. Taguchi technique identified best process parameters that exhibited highest hardness, ultimate tensile strength (UTS), and yield strength. ANOVA demonstrated the contribution ratio. The process parameters 100 MPa squeeze pressures, 20-s holding time, die steel material, and 750 °C melt temperature showed optimal value for hardness, UTS, and yield strength. © Springer Nature Singapore Pte Ltd. 2020.

Optimization of Squeeze Casting Process Parameters to Investigate the Mechanical Properties of AA6061/Al 2 O 3 /SiC Hybrid Metal Matrix Composites by Taguchi and Anova Approach

Advanced Engineering Optimization Through Intelligent Techniques Advances in Intelligent Systems and Computing

Squeeze casting is known to overcome the defects that incur during the conventional casting processes. The near-net shape manufacturing ability and potential to yield higher hardness are the capability of the squeeze casting provided technical parameters are accurately controlled. In this research, optimization technique for squeeze casting process parameter is established by Taguchi technique to explore the correlation among the hardness and tensile strength. Four different process parameters namely squeeze pressure, melt temperature, die temperature and holding time were selected to perform the experiments using L16 orthogonal array. The composites obtained for optimum cast conditions were squeeze pressure 100 MPa, holding time 30 s, melt temperature 750 °C and die temperature 100 °C exhibited better hardness and tensile strength. The identified process parameters provide a favorable condition for processing the alloys directly on the melt up to the time of complete solidification. The results indicate that there exists a strong correlation between hardness and tensile strength. © 2018 IOP Publishing Ltd.

Study on Squeeze Casting of Aluminum Matrix Composites—A Review

Currently, Aluminium (Al) 6061 material is used in Automobile and industry applications, Al 6061 matrix material gives good formability with excellent mechanical properties. Reinforcement of distribution is a major problem in some casting methods and to overcome this casting problem, squeeze casting technique was used in this research work, where Aluminium 6061 act as a matrix material and SiCp was used with different volume percentage. The effects of volume in ractions of reinforcements on the composite properties were investigated. The micro structural characterization results revealed a homogenous distribution of SiC particles in the matrix, which is almost free of pores can be obtained by squeeze casting method. The mechanical characterization revealed that the density, hardness and impact energy of composites increased while increasing the percent volume fractions of SiC particles. © TJPRC Pvt. Ltd.
