Specific Heat Capacities of Some Ternary Aluminides

Two different methods were employed to prepare samples of the ternary intermetallic phase: AlNi 2 Ti, and of Al 0.4 Fe 0.5 Ni 0.1 , Al 0.4 Fe 0.3 Ni 0.3 , Al 0.4 Fe 0.1 Ni 0.5 solid solutions, respectively. Alloys were then subjected to heat treatment for homogenization. Phase identification was made by XRD phase analysis and by the SEM BSE technique, and chemical composition was determined using the EDS method. Heat capacity measurements were made within a temperature range from 100 to 600 K using the DSC technique. Results were listed in tables and then fitted to a Kelley equation; an example of C p vs. T curve is given.
