When a heavily rolled specimen of austenitic Ni-Cr seels is bent, the hardness increases markedly beyond the expected effect of work hardening. This hardening, say, secondary work hardening, is generally obtained by slight application of a secondary working differing in type from the primary, and it is presumed that the strain age hardening and the secondary work hardening are induced by nearly the same cause, irrespective of presence and absence of the second phase, in other words, the hardening does not necessarily need a diffusion of solute atoms. The possible mechanism for the hardening may be as follows. During cold working, a large number of pile-up dislocations are formed around the barriers. After low temperature annealing, the dislocations move back and react with the other groups under the influence of the back stress originated in the pile-ups, so that they become difficult to move. The higher the dislocation density the easier the rearrangement. The martensite phase is a strong barrier, and its presence brings about a marked strain age hardening.
