Abstract
Influence of nanodispersed refractory compounds on structure and mechanical properties of heat-resistant alloys K403 and K4169 was investigated. Powders of chemical compounds TiN, TiCN, Y2O3 and their mixtures were used as the modifying agents. The results show that the modifying leads to general improvement of grain and carbide structure of heat-resistant alloys in casts. The grain average size in the cast decreased by 2-3 times, the carbide grains size decreased from 40-60 μm to 10-20 μm. This leads to significant improvement of the life at breaking load and LCF properties of the cast.
