“…The grain growth of the composite is suppressed by the ceramic additive which improves the hardness. Several studies have revealed that, according to the Hall–Petch rules, a fine grain size is beneficial for obtaining high microhardness [ 29 , 30 , 31 , 32 , 33 , 34 ]. In addition, the hardness of Al 2 O 3 embedded in soft aluminum can be attributed to the increase in the composite hardness.…”

Solid-state recycling, which involves the direct recycling of scrap metal into bulk material using severe plastic deformation, has emerged as a potential alternative to the conventional remelting and recycling techniques. Hot press forging has been identified as a sustainable direct recycling technique that has fewer steps and maintains excellent material performance. An experimental investigation was conducted to explore the hardness and density of a recycled aluminum-based metal matrix composite by varying operating temperature and holding time. A mixture of recycled aluminum, AA6061, and aluminum oxide were simultaneously heated to 430, 480, and 530 • C and forged for 60, 90, and 120 min. We found a positive increase in microhardness and density for all composites. The hardness increased approximately 33.85%, while density improved by about 15.25% whenever the temperature or the holding time were increased. Based on qualitative analysis, the composite endures substantial plastic deformation due to the presence of hardness properties due to the aluminum oxide embedded in the aluminum matrix. These increases were significantly affected by the operating temperature; the holding time also had a subordinate role in enhancing the metal matrix composite properties. Furthermore, in an effort to curb the shortage of primary resources, this study reviewed the promising performance of secondary resources produced by using recycled aluminum and aluminum oxide as the base matrix and reinforcement constituent, respectively. This study is an outline for machining practitioners and the manufacturing industry to help increase industry sustainability with the aim of preserving the Earth for our community in the future.

“…Aluminum and its alloys are considered to be a widely accepted material after iron and its alloy; apart from the structural applications, the former is considered to be a replacement for the latter based on its enhanced properties. Aluminum posse's low density thereby reducing the weight of the component and henceforth can be considered as a well suitable material in the field of civil, food processing, aerospace and automobile industries as weight is considered to be a major constrain during the design process [1][2][3]. Aluminum and alloys poses superior malleability, formability easing for the secondary processes such as hot rolling, forming etc., corrosion resistance and workability but its hardness and reduced wear resistance restricts its use to a large level in the field of transport industries [4][5][6].…”

In this study, pure aluminum (Al) powder metal (PM) compacts are sintered conventional or induction systems. PM compacts are sintered by furnace at 600ºC in 60 minutes in the conventional sintering process. In the other process, PM compacts are sintered by induction system at seven different sintering temperatures from 550 C to 610 C in 4 minutes. 2.8 kW, 900 kHz ultra-high frequency induction system (UHFIS) used for heating application of induction sintering process. Densities and hardness values are investigated for both processes. During these sintering processes, all energy consumption results are measured and calculated, then compared with each other. The effects of the sintering time increase in the induction sintering process on energy cost have been analyzed. Optimum sintering temperature of the induction sintering process is determined. It has been seen that the cheaper energy cost is obtained by the induction system for sintering application.
