Compocasting of an Aluminum Alloy Composite Containing B sub 4 C Particulate

摘要

A description of the compocasting process is given. Processing of metal matrix composites through the additions of nonmetallic particulate into a partially solidified, vigorously agitated metallic slurry is the key feature of the technique. This investigation is specifically directed at the fabrication of an aluminum -4 weight percent magnesium alloy containing uniform dispersions of boron carbide. The boron carbide imparts a dual property to the composite. It has high hardness and the ability to absorb neutrons. (ERA citation 06:030990)
