Gravity-Assisted Metallothermic SHS of Titanium Aluminide with Al–Ca Mixture as a Reducing Agent

Resumo

The gravity-assisted combustion synthesis of γ-TiAl from oxide raw materials by using Al–Ca mixture as a reductant was explored. The use of Al–Ca reductant markedly increased the yield of TiAl and decreased the amount of residual contaminants (such as oxygen, nitrogen, carbon) in target product.
