Creep of fully recrystallized and cold-worked Zr-1% Nb alloy upon rapid heating

Creep behavior of niobium-modified zirconium alloys

“…In a different study, Pirogov et al [29] reported a comparative account of the creep characteristics involving a fully recrystallized and a cold worked Zr-1Nb alloy. The former material had an average equiaxed grain size of 8 lm while the latter one had a 'fibrous' (presumably elongated) microstructure with an average 'fiber' (presumably grain) thickness of 3 lm.…”

“…Alymov and coworkers [26,[28][29][30]] generated a vast amount of high temperature deformation data in a wide range of conditions. The work was carried out in the single phase regime of the alloy at a temperature range of 377-597°C and a stress range of 10-150 MPa (2 · 10 À4 -4 · 10 À3 E) [26].…”
