WITHDRAWN: Material synthesis and spark erosion behavior of tantalum carbide based duralumin metal matrix composite

In recent days, the aluminium related metal matrix was an essential role in manufacturing sectors due to its substance properties. In the present topic, describes the duralumin composite was manufactured through stir casting method. The Tantalum Carbide (TaC) was a reinforcement material used to duralumin MMC. The substance composition was studied through Energy Dispersive Analysis of X-rays (EDAX). The machinability characteristics were analyzed through Spark Erosion Process (SEP). The Material Subtraction Rate (MSR) was measured by the variation of current, pulse on time and voltage. The parametric optimization was achieved by Taguchi technique and its effects were calculated by variance test.
