摘要：
The theory of thermally activated motion of dislocations yields a cusp in the graph of activation free enthalpy Delta G versus temperature when applied to FeNi-invar alloys. This is attributed to a magnetic induced hardening of FeNi. A theory of thermal activation is developed taking into account the magnetic hardening and the results are compared with CRSS and yield stress measurements of FeNi and FeNiMn alloys.
