Microstructure and mechanical properties of fly ash particle reinforced AA6061 composites produced by press and extrusion

“…Hence, composites reinforced with fly ash are likely to overcome the cost barrier for wide spread applications in automotive and small engine components. It is therefore expected that the incorporation of fly ash particles in aluminum alloys will promote yet another use of this low-cost waste by-product and, at the same time, has the potential for conserving energy-intensive aluminum and thereby, reducing the cost of aluminum products [10][11][12].…”

Recovery of Trace and Heavy Metals from Coal Combustion Residues for Reuse and Safe Disposal: A Review

“…23 CCRs have been used for extraction of zeolites, 2,24,25 mullite, 26 glass-like materials, 27 and composite materials such as plastic composites 28 and metal composites. 29 Several studies confirmed CCRs as potential adsorbents for removal of arsenic, boron, cadmium, chromium, fluoride, lead, mercury, nickel, pesticides, phosphate, zinc, color, and organic materials from waste water. 2,24 Golden and Wilder 30 proposed a conceptual commercialscale design to recover various raw materials such as alumina, ferric oxide, gypsum, and alkali sulfate salts from fly ash based on a direct acid leaching process.…”

Effect Of Compaction Pressure And Sintering Temperature On The Liquid Phase Sintering Behavior Of Al-Cu-Zn Alloy

“…One of the factors affecting the lower sinterability of P/M Al is very stable Al 2 O 3 layer in thickness of 50∼150Å on surface of water-atomized Al powders [6,7]. However, this oxide layer cannot be removed easily, resulting in limitation of mass flow between powder particles during sintering and in degradation of mechanical properties [8].…”
