“…It was reported that a cylindrical preform can be successfully compressed to a height reduction by 28-32% without fracture. Dikshit et al (2010) carried out cold upsetting experiments under unlubricated condition on cast and homogenized AA2014/SiC composites to study the effect of homogenization on deformation behavior. Orbulov and Ginsztler (2012) indicated that engineering factors such as the aspect ratio (height/diameter ratio) of the specimens and the temperature of the tests, have significant effect on the compressive strength and properties.…”

Composite metallic materials (CMMs) are prepared by dispersing copper particulates in aluminum matrix using stir-cast technique. Their behavior is compared with the alloy having similar composition. The effect of particulate composition is studied by varying the copper concentration between 5 and 15 wt%. Hardness increased with increasing particulate contents in both cast and homogenized conditions. Composites show a 13% drop in strength and 15% drop in strain compared to the alloy. With increasing reinforcement content, the strength increased and dropped. Agglomeration due to increased reinforcement contents may be the reason for the decrease in strength values. Microstructures corroborate the above results.

“…Figure 12 show macro-observations of Al6061-sea sand composite specimens after forging. The forging process has no effect on the particle size of the reinforcement; it simply influences the porosity, which becomes increasingly flattened [23]. Figure 13 depicts the microstructure of a specimen with 2% EC reinforcement and variations in forging.…”

The goal of this research was to determine the impact of cold forging on the mechanical characteristics and microstructure of Al MMCs at various sea sand percentages and forging deformations. The wettability of sea sand was improved by applying an electroless coating just before the stir-casting procedure. Using the stir casting technique, a composite material of Al6061 and sea sand was fabricated at several percentages of sea sand in weight, such as 2, 4, and 6%. In addition, open-die forging in cold settings was studied to learn more about the deformation characteristics of Al6061-sea sand composite. Composites were tested for density, porosity, microstructure, macrostructure, and hardness. The behaviour of microstructures was studied with an optical microscope. Brinell hardness readings taken according to ASTM E-10 were used to characterize the composite. The stir casting method was used to investigate and analyse the samples characteristics. More sea sand particles are distributed throughout the matrix as the composite’s density decreases. Increases in porosity are associated with an increase in reinforcement percentage, as this leads to more matrix-reinforcement surface contact and hence more porosity. The hardness diminishes with an increase in the proportion of sea sand particles. The mechanical qualities of the composite were enhanced by an oxide compound found on the sea sand. Evidence suggests that forging enhances mechanical and microstructure qualities.

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 ).
