The work hardening of Ge and InSb under compression is investigated, and the results are compared with similar tensile experiments. The results are similar for initial dislocation densities of about 10 4 cm −2 . The pronounced yield point is caused by dislocation multiplication, and is not related to oxygen pinning. The temperature and strain rate dependence of the lower yield stress is found to be in good agreement with a theory of flow based on quasi‐viscous dislocation motion and elastic dislocation interaction.
