In 2023, the global production of new red mud is expected to reach nearly 200 million tons, but less than 10% it currently being utilized in an environmentally friendly manner. To reduce sintering temperature alumina ceramics, a aid method used, as high-purity ceramics require solid-phase over 1700 °C. The metal oxides present are necessary components for high-performance composite ceramics. Composites were obtained by mixing and Al2O3. This study focused on mechanical properties wettability...
This paper mainly investigated the effect of Mn/Ag ratio on microstructure and room temperature high-temperature (350 °C) tensile mechanical properties as-cast heat-treated Al-6Cu-xMn-yAg (x + y = 0.8, wt.%) alloys. The alloy has α-Al, Al2Cu, a small amount Al7Cu2 (Fe, Mn) Al20Cu2 (Mn, Fe)3 phases. After T6 heat treatment, massive dispersive fine θ′-Al2Cu phase (100~400 nm) is precipitated from matrix. influences quantity size precipitates; when 1:1, precipitation reaches highest smallest....
The effects of red mud on the microstructures and high-temperature tensile properties ZL109 aluminum alloy have been investigated. Red mud/ZL109-based composite materials with added (a major byproduct industry), which has coated nickel by chemical deposition, prepared through gravity casting. results show that addition promotes alloy’s microstructure helps to uniformly distribute eutectic silicon. It also increases content heat-resistant phases, such as Q-Al5Cu2Mg8Si6 γ-Al7Cu4Ni phases....
The effects of the rare earth element La on microstructure and mechanical properties cast Al-5.4Cu-0.7Mg-0.6Ag alloys have been investigated through metallographic observation, scanning electron microscopy analysis, transmission microscopy, X-ray diffraction, tensile testing. present form action mechanism analyzed. findings indicate that inclusion trace amounts markedly diminishes grain size in Al-Cu-Mg-Ag alloy. Furthermore, as content increases, alloy's strength is significantly improved....
The utilization of red mud in the production ceramic products represents an efficient approach for harnessing resources. Composite ceramics were prepared from Al2O3, mud, and Cr2O3 by atmospheric pressure sintering, phase composition microscopic morphology composite investigated XRD, SEM, EDS. flexural strength fracture toughness measured three-point bending SENB methods. results showed that sintered at 1500 °C with addition 1.5 wt.% had a 297.03 MPa, hardness 17.44 GPa, densification 97.75%...
Abstract The 6016 aluminum alloy was artificially aged at different aging temperatures and time. effects of Cu on microstructures, hardness, tensile properties corrosion resistance were studied. results show that the grains added are refined new phase Q (AlCuMgSi) appears, mechanical in T4p state improved time to reach strength peak is shortened. intergranular decreases with time, turns pitting later stage, it suggests reduced.
