Sažetak
The authors have performed a joint analysis of the experimental data on high-temperature mechanical properties and fracture patterns of low- and mediumalloyed niobium-based alloys (Nb-W-Mo-Zr), produced by vacuum-arc melting, in the recrystallized and cast conditions under uniaxial tension. The characteristics of short- and long-term static strength, plasticity, and creep resistance of the materials under study in a high-temperature region (0, 5 - 0, 8)• Т mp have been found to correlate closely. Both partial and generalized empirical relations between the high-temperature strength of the alloys and their ultimate strength and relative elongation in short-term static tension, which are unaffected by the structural state and fracture behavior of the material, have been obtained.
