| Abstract Scope |
Self-propagating High-temperature Synthesis utilizes the local heat of an energetic solid-state reaction to propagate the reaction through a mixed chemical body. For aluminum-titanium carbide composites the SHS process forms titanium carbide from elemental titanium and carbon powders as they are added to an aluminum melt which is then die cast. The SHS synthesis of TiC in aluminum increases the workable volume fraction of TiC (30-60 Vol%) in the aluminum alloy and reduces oxide impurities at the Al/TiC interface. The engineered properties design target is to match the wear, hardness, and compression strength properties of cast iron with the Al/TiC composite. Reducing the ignition temperature of the titanium/carbon reaction is done by adding low ignition temperature, chemical oven reactants to the elemental Ti and C powders and is important to reducing the cost of the manufacturing process and equipment and adapting the process for magnesium/TiC composites. |
