The influence of modification of heat-resistant nickel-based alloys on the crystallization kinetics of alloys was established by the methods of thermal analysis.This effect is expressed in the increase in solidus temperature and, as a consequence, narrowing the crystallization range of the HR Grip alloy, the increase in the growth rate of a solid solution, and change in the temperature of precipitation of eutectic and strengthening phases.As a result, the use of modification with refractory particles makes it possible to exert an additional effect Lug Nuts on the structure and properties of nickel-based alloys without additional heat treatment.
