Optimization of Squeeze Casting Process Parameters Using Taguchi in LM13 Matrix B4C Reinforced Composites

Aluminium metal matrix composite has widely used in aerospace and automobile industry due to its high strength to weight ratio. Aluminium LM13 matrix B4C reinforced composites are mainly manufactured by Squeeze casting process. The present work optimizes squeeze casting process parameters using Taguchi method. The control factors used for the experiments were Squeeze Pressure, Die Preheat Temperature and weight percentage of Boron Carbide (B4C) along with multiple performance characteristic of Hardness, Ultimate Tensile Strength (UTS) and Yield Strength (YS). The L27 orthogonal array was used for experimental design. Analysis of variance (ANOVA) is used to determine the significant factor and found out that Squeeze pressure is the most significant factor followed by percentage of B4C.
