REVERSED-BEND TESTS OF ABS-C STEEL WITH AS-ROLLED AND MACHINED SURFACES.
Abstract
Comparative tests between bars with as-rolled and with machined surfaces show a small difference in the compressive prestrain needed to exhaust the original extensional ductility of the steel, as this is determined by the reversed bent test. Machined bars show a higher exhaustion limit (prestrain) than as-rolled bars by 0.03 at 70 F and 0.06 at -16 F. Stress calculations show that the most brittle fractures may occur at applied elastic macroscopic stresses as low as about 50 ksi at 70 F and about 30 ksi at -16 F. Highly ductile bars sustained a stress close to 90 ksi at both test temperatures. (Author)
