“…It was observed that the multi-step sintering process reduced the phenomenon of cracking around the places with highest density. Later on, the effect of sintering time intervals and temperature on workability behavior of Al-SiC matrix P/M composite was studied by Bensam et al [4]. It was observed that increase in sintering temperature reduces the pore size, which in turn increases the formability stress index value of the composite.…”

Aluminium-based metal matrix composites (MMC) are very popularly used in aircraft, automotive and armaments industry because of their high young's modulus, specific strength and enhanced wear properties. It is to be noted that there are many methods available for the production of aluminium-based MMCs. The present paper aims at optimization of process parameters related to the powder metallurgy-based process of producing Al-SiC MMCs with the help of two non-traditional optimization algorithms, namely genetic algorithm (GA) and artificial bee colony (ABC) algorithms. It is important to note that the input process parameters related to the powdermetallurgy process, such as percentage of reinforcement, sintering temperature, compacting pressure and sintering time are considered as inputs and the properties of the composite produced, namely sintering density and micro-hardness are treated as outputs. The non-linear regression equations related to the sintering density and micro-hardness in terms of input process parameters have been developed after utilizing the experimental data available in the literature. The two objectives (that is, sintering density and micro-hardness) in this process are combined to form a single objective and the problem has been solved as a maximization problem with the help of GA and ABC. It has been observed that the optimal values of the input process parameters obtained by the two optimization algorithms are comparable.

Effect of TiO 2 in aluminum matrix on workability behavior of powder metallurgy composites during cold upsetting Aluminum-based metal matrix composites withv arious weight percentages (0, 2.5, 5, 7.5, and 10) of TiO 2 reinforcementw eres ynthesized by means of powder metallurgy and theirw orkability behavior under triaxial stress-state conditions was completely studied during cold upsetting. Green cylindrical compactswere made using a400 kN hydraulic press with suitable punch and die, sintered at (590 ±10) 8 Cf or ap eriod of 3h,f urnace cooled and machinedtoobtain samples with 0.5 aspect ratio. The cold upset tests were carriedo ut in steps of 10 kN and the results were studied for the workability behavior of the composites. The formability stress index ( b )a nd stress ratio parameters ( r z / r eff ), ( r m / r eff ), and ( r h / r eff )w ere calculated for all composites and correlated with true axial strain(e z ). It was observed that the addition of TiO 2 to the Al matrix material increases the stress ratio parameters and formability stress index ( b ).

“…Hence, the materials in the available form are either alloyed or reinforced to realize the materials with enriched properties. Materials with less weight are greatly attracted by both the researcher and industrialists, induced the development of metal matrix composite with good mechanical strength, wear resistance and corrosion resistance (Bensam Raj et al , 2012; Mahamani et al , 2012; Saravanan et al , 2017). Particularly, magnesium appealed most industries as it owns low density, good strength and stiffness (ASM International, 1990).…”

Purpose The purpose of this study is to analyse and optimize the wear parameters of magnesium metal-metal composite. Materials with lesser weight attract both the researcher and industrialists, as it exhibits the performance improvement in the automotive and aerospace industries. The enrichment of mechanical and tribological properties of the existing magnesium focussed the development of new metal–metal composite. Design/methodology/approach Metal–metal composite with magnesium matrix was synthesized through the disintegrated melt deposition technique with the addition of titanium, aluminium and boron carbide particles. The wear performance of the composite was experimented with the dry sliding wear test by considering load, sliding velocity and sliding distance. Findings The wear rate of the composite is analysed statistically, and the significance of wear parameters on the wear performance of metal–metal composite is observed. The worn pin surface and the wear debris collected during the wear experiments were exposed to the microscopy analysis to seize the dominating wear mechanisms. Originality/value The wear performance of the developed magnesium composite was analysed and discussed in detail with the support of scientific evidence, i.e. worn surface and debris analysis express the wear mechanisms.
