3 of the articles, always assuming, of course, that the temperatureof the test-piece and of the articles were the same at every stage.For instance, if the piece were to spring back, or recover its originalposition to the extent of only one-twentieth of its original deforma-tion, the degree of… … Fig. 3. But if, instead of permitting the test-piece to spring back, weapply a constant stress of small amount in such a way as to tendto increase the original deformation, then, when the release ofstress by annealing has proceeded far enough, the deformation willbegin to increase continuously, and…
