Abstract
The creep parameters of solid nitrogen are measured in the temperature range 32.1–39.9 K which includes the polymorphic transition point Tαβ = 35.61 K. An appreciable increase in the steady state creep rate of the samples is detected during the transition from the low-temperature cubic α-phase to the high-temperature hexagonal β-phase. This effect is explained by the fact that, despite a decrease in the number of slip planes (which could lead to increased rigidity of the crystal), two other factors play an important role in determining the enhanced plasticity of the β-phase. One of these factors is the disappearance of orientational ordering, which affects the plasticity of the material. The other factor, which is also related to the absence of orientational ordering, is a substantial difference in the structure and mobility of dislocations in these phases.
