Abstract
Here, the investigation is spotlighted on the aluminium alloy from the waste materials of the automobile bumpers which is a reinforced metal matrix composite created with 5 percentage of nickel and 5 percentage of magnesium oxide through the stir casting method. The stir casting process inputs parameters such as pressure of squeezing, time of squeezing, and speed of stirrer which were optimized based on the two mechanical properties’ outcome such as the tensile strength (TS) and Rockwell hardness. There are nine different experiments which were conducted based on the L9 array. The Taguchi method is used to identify the optimum input values for the greatest result of the processing condition by Minitab software. The responses‐based parameters were ordered based on the rank identified through the investigational effects. Finally, the optimized input consideration values and the linear equations are recommended for both the considered outputs as conclusions.
Highlights
Around the world, scraps of the automobiles are increased day by day, so the effective utilization of the wastes of automobiles, such as accidental bodies, damaged bodies, and replaced bodies, can be reusable after recycling
Especially the automobile bumpers which are made up of aluminium were chosen for this investigation
Christy et al [1] completely explained about optimization techniques used for the input parameters of the squeeze and stir casting with the help of the Taguchi technique. ey explained with the various microstructure diagrams and comparison plots. ey used the four input parameters for the four output responses. e basic things of the optimization techniques for the various machining processes of composites such as various proportions of aluminium with zirconium carbide composite [2], several combinations of aluminium with silicon carbide [3], and numerous combinations of aluminium with nanomaterials [4] in the same way machining such as parameters of the laser welding
