The true stress (s) ± true plastic strain (e) data of a type 316LN austenitic stainless steel tested at nominal strain rates in the range 3610 25 ± 3610 23 s 21 and temperatures of 300 ± 1123 K were analysed in terms of ¯ow relationships proposed by Hollomon, Ludwik, Swift, Voce, and Ludwigson. The applicability of the particular ¯ow relationship is discussed in terms of `complete' and `applicable' range ®ts of the experimental s ± e data. At all strain rates, in the case of the complete range ®t, the Ludwigson equation followed the stress ± strain data most closely at 300 K, while in the temperature range 523 ± 773 K, the ¯ow behaviour was described equally well by both the Ludwigson and Voce equations. In the temperature range 823 ± 1023 K, the Voce equation described the ¯ow behaviour most accurately in the case of the complete range ®t of s ± e data at all strain rates. The analysis of s ± e data employing the Ludwigson equation in the applicable range ®t covering low and intermediate strains, and the Hollomon equation at high strains provided close simulation of the observed ¯ow behaviour in the temperature range 823 ± 1023 K. At high temperatures of 1073 and 1123 K, the Ludwigson equation reduces to the Hollomon equation. The variations in different ¯ow parameters of the Ludwigson and Voce equations with temperature and strain rate exhibited anomalous behaviour at intermediate temperatures because of dynamic strain aging.MST/4679
