Interrelation between strength and creep in niobium base alloys

The common analysis of experimental data on high-temperature mechanical properties of low- and medium-alloyed niobium melts in the vacuum-arc melting of the Nb-W-Mo-Zr system and in the recrystallized and cast states under the conditions of single-axis tension is carried out. There exist close correlation bonds between the characteristics of short-term, continuous static strength, plasticity and creep resistance for the studied materials in the high-temperature area. Both partial and generalized empiric dependence, binding the melts heat-resistance indices with their time resistance and relative elongation and short-time static tension, independent of the materials structural state and destruction character, are obtained
