Abstract
This study determined the serrated yielding type for 316L(N) SS due to the Portevin-Le Chatelier effect under particular temperature conditions with the range of 24 to 655 °C at 10-5/s of plastic deformation rate. The 316L(N) SS was loaded by tensile test apparatus equipped with a three-zone furnace. The cylindrical specimen was put at the centre of the furnace. Since the test was conducted at various temperatures, a thermocouple was attached to the surface of the specimen. After the test, the engineering stress-strain curve was plotted, and the serrated yielding was observed. The results showed that the type A, B, D, and E were identified for a particular temperature. Type B was identified at the low-temperature region, and type A was identified at the high-temperature region. In addition, the work hardening rate curve was plotted to describe the plastic deformation characteristic.
