Abstract

Formation of aluminum and titanium carbides was observed in Al-Ti mechanical alloys prepared with stearic acid as process control agent. Thermal analysis showed that Al₄C₃ forms as a result of carbon contamination together with Al₃Ti phases, which react at ∼900 °C to form TiC_1-x and Al melt. This transition causes a previously unexplained equilibrium transition.
