Description Tensile specimens of Type 316L, stainless steel, containing boron and having grain sizes in the range 3.1 to 103.8 mu m, were deformed at 24, 400 and 700 degrees C at a constant strain rate of 1 x 10(-4) s(-1). The flow stress (sigma) varies with strain (epsilon) and grain size (d) according to the Hall-Fetch (H-P) type relationship sigma(epsilon) = a epsilon(n) + b epsilon(m)d(-0.5) with the H-P parameters (sigma(0) and k) interrelated through the constants a, n and b, m. The presence of boron affects the flow stress and changes the H-P parameters, depending on test temperature. The dislocation density increases with temperature due to dynamic strain ageing, which leads to some anomalous effects of grain size at 700 degrees C. (C) 1997 Acta Metallurgica Inc.
