Book excerpt: Excerpt from The Effects of Cold-Working on the Elastic Properties of Steel There is one difficulty about the explanation of the harden ing of metal by plastic strain, as given by the conceptions ex plained above, which requires brief mention. This lies in the fact that the hardening produced by plastic strain is, in certain cases at all events, unidirectional. For instance, a piece Of steel which has been 'hardened, ' has attained a raised yield point and apparently raised elastic limit, as the result Of tensile overstrain, is not really hardened in every way, for, if it is tested in compression, it is found that for stresses Of that kind the apparent elastic limit has been lowered, so that the total range of stress of elasticity, from the limit in compression to the limit in tension, has not been materially altered. It is difficult to see how the formation Of hard amorphous layers on surfaces of slip can account for softening of the metal in relation to com pression while producing hardening as against tension. It may be, Of course, that there is something directional about the manner in which the crystalline arrangement is broken up on the Slip Surfaces, so that a configuration results which allows Of Slip in one direction but not in another.
