Subject of the research are samples based on platinum and aluminum and deformed by using high pressure torsion. The purpose of the work is to develop a technique to produce PtAl2 intermetallic compounds with subsequent study of the microstructure and mechanical properties of the obtained samples. Research methods: carrying out mechanical alloying, studying the microstructure, conducting mechanical hardness tests of samples. As a result of the research samples in the form of plates containing an intermetallic phase were obtained by high pressure torsion the starting metal powders. Samples were examined using a scanning electron microscope and an X-ray diffractometer. The microhardness of the samples was tested. X-ray phase analysis showed the presence of intermetallic in deformed samples. The novelty of the study is to obtain intermetallic using high pressure torsion. Application field: the obtained results can be used to create PtAl22 intermetallic compounds for aircraft and machine building.
