Optimization on Powder Metallurgy Process Parameters on Nano Boron Carbide and Micron Titanium Carbide Particles Reinforced AA 4015 Composites by Taguchi Technique

Abstract

Aluminium metal matrix composite is developed using powder metallurgy, with number of different operational factors considered. The three most important operational factors are sintering time, sintering temperature, and compaction pressure. Investigations are conducted using L9 orthogonal array as the experimental design. Density, Vickers hardness, and compressive strength are determined through experiments. The S/N ratio based on Taguchi’s law and a number of anomalies accomplished were used to determine the effect of individual input parameters (ANOVA). The main effect plots identified the optimal parameter settings for obtaining a less density, a higher hardness, and a higher compressive strength. In addition, the ANOVA analysis confirmed that the best metal matrix composite material is produced at the optimal sintering time and average temperature and compaction pressure for generally classified levels.

Experimental and optimization study of powder metallurgy process parameters of magnesium base AZ31 alloy using taguchi method

“…The hardness augmented, and the wear rate reduced upon raising the sintering time. And, there isn't plentiful literature accessible on the Mg-based materials re-processing via the procedure of Burke and Kipouros reported a review of the re-processing and foaming of Al-based materials, clarifying the various approaches of re-processing the aluminum via PM; such approaches can be utilized for re-processing the Mg-based materials [17].Alrebdi et al [18] evolved an Al metal matrix composite employing the PM procedure. The studies employed the orthogonal array (L9) as the investigational design.…”
