A statistical model was proposed in order to account for strength anomalies in L12 alloys. This was based upon a competition between the locking of super-dislocations in Kear-Wilsdorf locks, and the by-passing of these locks by macro-kinks. From the statistical distribution of macro-kink heights, it was deduced that the population of mobile dislocations was exhausted with increasing efficiency as the temperature increased. This yielded either exhaustion creep at a constant applied load, or a strength anomaly under constant strain-rate conditions.
