Performance of Aluminium / Vinylester Particulate Composite
2010 •
Matthew Reushle
The performances of aluminum /vinylester particulate-composites were studied in detail in order to investigate its suitability for engineering applications. This study examined the suitability of atomised aluminum particles for particulate reinforcement of a vinyl ester resin. Mechanical properties were obtained for the composite by testing various percentages of aluminium powder (75-150 m) and vinylester resin. It has been found that the inclusion of Al powder has not significantly changed the properties of vinylester resin, however an improvement in the ductility of the composite has been recorded. The optimal performances of the composite were exhibited by 15% Al composition. The properties of the particulate composites were modeled using numerous empirical models. Unfortunately a significant difference was found between some of the experimental and predicted properties of the Al/vinylester particulate composite. This paper intends to detail the variation of mechanical propertie...

10:30 AM Invited Manufacturing Challenges to Reduce Weight in Transportation Applications: Alan Taub; University of Michigan New solutions are needed to reduce the weight of the machines that move people and goods on land, sea and air. The potential for reducing weight using high-strength steels, aluminum, titanium and magnesium alloys is well established. Key is to achieve the weight reduction economically and ranges from about $5/kg saved for automobiles to over $500/kg saved for aircraft. This requires optimizing the material properties and developing robust, scalable manufacturing technologies. Lightweight Innovations for Tomorrow (LIFT) was established to accelerate the adoption of advanced metallic structural components and serves as the bridge between basic research and final product commercialization. Our industry partners in collaboration with an extensive network of universities and the national and federal laboratories are developing these advanced manufacturing processes...

Effects of applied pressures and calcium contents on microstructure and tensile properties of squeeze cast magnesium-aluminum-calcium alloys

Mohsen Masoumi
In this study, the effect of applied pressure levels and calcium contents on the microstructure and tensile properties of squeeze cast magnesium alloys AMC50X has been investigated. The results indicate that the tensile properties of AMC501 alloy including ultimate tensile strength (UTS), yield strength (YS), and elongation (Ef) increase as the applied pressure increases from 3 MPa to 90MPa. The improvement in tensile properties can be attributed to casting densification. As the calcium content of AMC50X increases from 0 to 4%, the UTS and Ef decrease dramatically at room temperature, but the yield strengths of the alloys improve slightly. At 150 °C, however, the UTS of the alloys increases with increasing the Ca content. The variation of Ef and YS of the alloys at 150 °C are similar to those at room temperature. The results of microstructural analysis indicate that calcium addition has a grain refining effect on the base alloy AM50A.

AA7075-ZrO2 Nanocomposites Produced by the Consecutive Solid-State Process: A Review of Characterisation and Potential Applications

Solid-state recycling is a direct conversion method for producing metal chips, whereas the materials are plastically deformed into the final product without melting, offering lower energy consumption and metal waste. This technique was reported for fabricating aluminium-zirconium oxide (Al-ZrO2) composite and it was widely used to avoid metal chips bounding at high temperatures during the extrusion process. Aluminium alloy (AA7075) is known for its high yield strength of more than 500 MPa under optimum ageing conditions. However, AA7075 can be further reinforced by zirconium oxide nanoparticles when needed for high-performance applications. Hot extrusion is used to obtain better mechanical properties of composite materials. The equal channel angular pressing (ECAP), a severe plastic deformation technique, was recently used to produce bulk and light recycled metal chips, such as porosity-free and ultra-fine-grained aluminium nanocomposites (ANCs). Heat treatments (HT) and ECAP post h...
