A Short Review on Al MMC with Reinforcement Addition Effect on Their Mechanical and Wear Behaviour
Advanced mechanical and wear properties and applications of composites with bases of light weight metals have led to the need of aluminium (Al) metal matrix composites (MMCs). In today’s time aluminium (Al) metal matrix composites (MMCs) are considered the most potential material for structural and functional applications. Composite materials with aluminium matrices are used in defence, aerospace, automotive and aviation, thermal management areas. Beneficial properties with reduced prices have enlarged their applications. To obtain desired physical and mechanical properties like high hardness, high strength, high stiffness, high wear, abrasion and corrosion resistance Al is reinforced with different metallic, non-metallic and ceramic elements. Al MMCs are used to make piston, connecting rod, engine cylinders, disc and drum brakes where wear has a great role in the functioning of these components as excessive wear of the mating components sometimes leads to catastrophic failures. Improvement of mechanical, especially tribological properties of hybrid composites were provided by the use of certain reinforce materials such as SiC, Al2O3 and graphite. Hence the present chapter presents a review on aluminium metal matrix composites (MMCs) reinforced with different particulate, whisker, fibres reinforcements highlighting their effect on physical, mechanical and wear behaviour of Al MMCs.

Analysis of the Effect of Heat Treatment Conditions of a Ferritic Stainless Steel on Residual Stresses and Tribological Behavior
In recent years, the scientific community has shown a great interest in the study of the wear performance of metallic materials under different test conditions, together with the measurement of residual stresses. Thus, the objective of the present work was to analyze the effect of heat treatment on residual stresses and tribological behavior of P410D ferritic stainless steel. The results showed that, with the increase in hardness of the material—derived from different heat treatment conditions, the resistance to micro-abrasive wear of P410D ferritic stainless steel increased, characterized by a decrease in wear volume. The residual stresses reported were “tractive”; additionally, it was observed that the lowest residual stresses values were related to the lower wear volumes values.
