摘要：
J. Malcharczikova, M. Pohludka, and M. Kursa (VSB-Technical University of Ostrava): Microstructure Characteristics of Ni3Al Based Intermetallic Compounds Observations were made in orientated state of non-alloyed intermetallic Ni3Al based compound (22-25 at.% of Al). The samples were solidified by Bridgman's technique. It was established that Ni22Al samples contained formations of Ni3Al (gamma') and solid solution of nickel (gamma), Ni25Al samples contained Ni3Al only. The differences of mechanical properties were not manifested at measurement of micro-hardness, which is for all the samples approximately within the interval from 240 to 260 HV 0.05.
