Study on the Interface Bonding and Bending Fatigue Properties of Aluminum Alloy Foam Sandwich () 摘要:Foam materials have many attractive properties because of their low-weight and cell structure. By sandwiches with an aluminum-foam core, it is possible to obtain higher structural stiffness and rigidity, maintain stability against buckling and additionally make use of the high energy......
been paid to the research of LFC process of magnesium alloy in recent years[3, 6-11]. During the LFC mold filling processing, the endothermic degradation of the foam pattern from the moving metal-foam interface produces a chilling effect on the liquid metal. As a result, it influences the temperature field after mold filling and solidification modes of castings. Currently, the heat transfer......
Microstructure and mechanical properties of Mg-Gd-Y-Zr alloy cast by metal mould and lost foam casting LI Ji-lin, CHEN Rong-shi, KE Wei State Key Laboratory for Corrosion and Protection... of Mg-10.1Gd-3.74Y-0.25Zr (mass fraction, %) alloy (GW104 alloy) cast by metal mould casting (MMC) and lost foam casting (LFC) were evaluated, respectively. It is revealed that different forming modes do......
on a balance and measuring their dimensions by a digital caliper. Relative density could be calculated through the ratio of Al-Si closed-cell aluminum foam density to dense metal density. The cell...; (3) where ρ*, E* and are the density, elastic modulus and strength of the foam; ρs, Es, σy are the density, elastic modulus and strength of the metal matrix. C1......
is a low-cost technique for manufacturing complicated and near-net-shape castings. In the LFC process molten metal is poured into a foam pattern that has been coated with a refractory material... an EPS foam plank using a hot wire cutter and had a nominal density of 0.020g/cm3. The molten metal displaced the Styrofoam pattern with precise dimensional accuracy. Gases produced due......
