Review—Parametric Study and Various Strategies of Aluminium Metal Matrix Composites Fabricated by Friction Sir Processing

Abstract

There is a dynamic shift underway from traditional technology due to the revolution of industries. Conventional techniques are hindered and advanced technologies are coming into existence. Friction stir processing is one of the processes spreading its usage across the field. Formation of surface composites with inclusion ceramics is one of the greatest advantage investigated in this study. Metal matrixes are far better than alloys as properties which are desired could be easily achieved with varying composition. Aluminium-based composites possess higher strength to weight proportion which is highly recommended in the field of aerospace and automobile industry mainly due to its lower density. This study deals with various process parameters that researchers have come across till date related to FSP. Furthermore, research based on friction stir processing of aluminium reinforced with ceramics are discussed mainly based on SiC or B4C. This comprehensive review tries to fill the gaps in developing a deep understanding of aluminium-based composites when friction stir processed ceramics improves mechanical as well as wear properties of material to a larger and extent and can easily replace conventional materials leading to cost effective as well as free from defects.

Microstructure and Wear Analysis of Copper-Graphite-Titanium Carbide Hybrid Metal Matrix Composites Fabricated by Powder Metallurgy (P/M) Technique

“…A good amount of interfacial bonding is found between the Cu and ceramic reinforcements which thus accounts for an increased hardness of sample with a modest concentration of Gr.-TiC. [24][25][26] Figure 14 displays the compressive strengths of different specimens (Pure Copper and Composites) as a function of the concentration of Gr.-TiC. Specimen having 5 wt.% of Gr.-TiC shows the highest value of compressive strength, and it gradually reduces with an increase in Gr.-TiC reinforcement, as shown by the experimental data.…”
