The reinforcing impact of TiB2 nanoparticles (TiB2np) and alumina nanoparticles (Al2O3np) in an aluminum (LM14) alloybase matrix composite was studied. Stir casting was used to create the hybrid aluminum matrix-based nanocomposites(AMNC) specimens. When nanoparticles are mixed into a matrix, the resulting material is stronger than LM14 aluminumalloy. The results of the EDAX and SEM studies clearly illustrate the distribution of reinforcing particle sizes. Compressionand density tests on AMNC specimens are contrasted with those on LM14 aluminum alloy tests. The increase in theirmechanical characteristics is influenced by the proportion of reinforcements in the matrix phase. Nanocomposites based onan aluminum matrix outperform the metal in terms of compressive strength, density, and abrasion resistance.

Metal-based composites, such as those used in the aerospace and automotive industries, are becoming increasingly popular dueto their intrinsic advantages like higher strength-to-weight ratios and less wear rates. An aluminium 7475 alloy based on MMCwas tested using the Taguchi design of the experiment. The major goal is to use the Taguchi method to anticipate the bestparameters for castings with the highest tensile strength and hardness. Good quality castings can only be made with precisecontrol of the process parameters. Stir casting was employed to make test samples with varying reinforcement weightpercentages, stirring speeds, and processing temperatures. Analytical variance and orthogonal arrays were used to explore theinfluence of process factors on the desired attributes. The Taguchi method was used to identify the best settings for maximizingthe mechanical characteristics of composites. The fundamental objective of this investigation is to find how various parameterscan be altered to produce defect-free castings with the necessary tensile strength and hardness for certain applications. TheTaguchi optimization method was demonstrated by conducting a test at the optimal level of processing parameters.
