Abstract
Tensile deformation behaviour of AISI 316L(N) stainless steel was investigated over the range 298 to 1023 K. The yield and tensile strength were found to meet the minimum values mandated by RCC-MR, the French design code for fast reactors. The tensile flow behaviour was modelled using Ludwigson and Voce equation. Ludwigson equation could model the flow behaviour adequately before the onset of saturation at temperatures >823 K. Voce equation could model the flow behaviour between 298 and 1023 K. The physical basis for the variation with respect to strain rate and temperature of the constants obtained by modelling the flow curve using Ludwigson and Voce equation is discussed.
