Abstract:
We have studied phase-formation processes in mixtures of Cr and Al (20 wt %) powders in the
course of mechanical alloying (MA) and the phase transformations of the samples during subsequent annealing
at temperatures of up to 800°ë. The resultant x-ray amorphous intermetallic phases were identified by a differential
dissolution method, which allows one to follow the formation of x-ray amorphous and partially crystallized
phases. During MA of Cr + Al mixtures, the first to form is x-ray amorphous Cr4Al, which then converts
to partially crystallized Cr2Al through reaction with aluminum. The peritectoid decomposition of Cr4Al during
heating of the MA samples is accompanied by heat release at 330–350°ë. Heating to 420°ë leads to the formation
of Cr5Al8. At 800°ë, Cr5Al8 reacts with Cr to form Cr2Al.
