The tensile, compressive, bending and hardness tests are shown about specimens of usual carbon steel (0.22% C) after plastically deformed by statical tension and compression. The experimental results are as follows: (1) The proportional limit in the direction of pre-working is about 80-90% of the actual pre-working stress, but decreases about 30-50% of that in the opposite direction due to the Bauschinger effect. (2) On the bending test of the tensile pre-worked specimens, yielding starts at first on compression side of bending, and then the proportional limit on the compression side rises to about 2-3 times of the compressive proportional limit obtained after tensile pre-working. (3) Reversely to above mentioned, on the bending test of the compressive pre-worked specimens, yielding starts at first on tension side of bending, and then the tensile proportional limit rises to about 2 times of that obtained by tension test. (4) The difference of the proportional limits between tension and compression side of bending is about 10%, and this value is much smaller than that found in the case of the tension and the compression test of the pre-worked specimens. (5) The smaller the degree of pre-working is, the larger hysteresis loop for the first cycle of bending is obtained. Comressive residual strain is found after bending in total cross section of specimen pre-worked by tension, and tensile residual strain is found by compressive pre-working. (6) When the specimen is pre-worked up to about 10% strain, the hardness value does not rise for 5-10% strain in opposite direction to the pre-working, and shows work softening. (7) On the other hand, the work softening is not clear for smaller pre-working of about 3-5%, and the specimen shows work-hardening somewhat similar to that of virgin metal. |
