Popis:	We study the influence of the conditions of impact compaction and heat treatment on the physicomechanical properties and structure of intermetallic compounds. We carried out the procedure of compaction by impact hot pressing of a Fe–14Al (wt.%) intermetallic compound prepared from iron and aluminum powders at temperatures of 1050 and 1150°C, as well as the procedure of annealing of compacted specimens at 1250°C for 60 min and at 1350 or 1450°C for 20 min. It is shown that the procedure of impact hot pressing makes it possible to obtain practically porousless specimens at temperatures of compaction equal to 1050°C and 1150°C. We managed to get high-quality contacts between intermetallic particles and to improve the mechanical properties as a result of annealing at a temperature of 1350°C.
