Conclusions As a result of alloying with niobium, the thermal stability of the ribbons investigated increased by 100–150°C over the value for the standard R6M5-type steel containing the same amount of boron. At the same time, the transition temperature of the ribbons to the plastic state almost did not change upon alloying with niobium. Based on an analysis of the thermal stability of the alloys investigated, we may assume that simultaneous introduction of niobium and boron into them increases the stability of the structure which, in turn, leads to an increase in the thermal stability. This is, apparently, caused by the homogeneous and uniform distribution of the carbides and carboborides of niobium. For an explanation of the mechanism of the thermal stability of the alloys investigated, we need further detailed investigations. However, the generation of a combination of properties of these alloys attained by combined alloying makes them promising for practical applications.
