Book Description
Thermal strain hardening of nickel-free structural steels was studied, using steel specimens smelted in a 200-kg open induction furnace. The specimens were homogenized for 10 h at 1180C and reduced to 37 x 37-mm size. Thermal strain hardening was carried out at 850 and 500C. The mechanical properties, austenite concentration in the specimens, and the size of martensite needles in the latter were determined, and the experimental results tabulated. It was found that thermo-mechanical treatment of specimens at 500C with 74 percent degree of deformation yielded steel with a strength limit of 275 kg/sq mm. Best results were obtained when the specimens were tempered at 100C. It is suggested that the observed strengthening effect is due to a decrease in the size of martensite needles in the specimens.
