Aluminum and Aluminum Alloys Casting Problems

Aluminum castings have played an integral role in the growth of the aluminum industry since its inception in the late 19th century. The first commercial aluminum products were castings, such as cooking utensils and decorative parts, which exploited the novelty and utility of the new metal. Those early applications rapidly expanded to address the requirements of a wide range of engineering speci...

A Guide to Aluminum Casting Alloys

The specification of an aluminum alloy for a cast component is based upon the mechanical properties it can achieve. For the designer and purchaser, it is vital to understand that the properties obtained from one particular combination of casting alloy, foundry practice and thermal treatment may not be identical to those achieved with the same alloy in a different foundry or with a different the...

Detection of Floating Grains in DC Aluminum Casting

Free-moving “floating” grains have been linked to macrosegregation in direct-chill (DC) aluminum castings. The presence of these grains in the sump of a solidifying ingot has been acknowledged based on measurements of cast microstructures and by recent work using a turbulent jet to suspend solute-poor grains and minimize macrosegregation. Experiments in this study were designed to sample grains...

Corrosion Resistance of Directionally Solidified Casting Zinc-Aluminum Matrix

Study on Iraqi bauxite ceramic reinforced Aluminum metal matrix composite synthesized by stir casting

For the past decades researchers are showing immense interest to investigate the natural advantage of preparation of composites from minerals such as bauxite particles, and proved their effectiveness as cost effective reinforcing agents in fabrication of high performance composites. This study, is a new attempt in using the Iraqi natural bauxite powder with different proportions (2wt%, 4wt%, an...
