The plasticity of solid parahydrogen with lowered deuterium contents under step-wise uniaxial extension
at liquid helium temperatures 1.8–4.2 K has been investigated. Work hardening curves for single crystals
have been measured. Maximum possible values of sample’s elongation without their fracture at minimum
stress values have been reached. Features of super-plastic irreversible deformation of samples were
observed. Anomalous temperature dependence of deformation parameters has been found. The character of
this anomaly exhibits evidence of the coherent motion of dislocation kinks in Pierls relief, modified by residual
ortho- and deuterium impurities.
