摘要：

Worked specimens of type 317 stainless steel, deformed in torsion to fracture in the temperature range 900-1200 degree C exhibited flow curves which increased to peaks and decreased to steady state regimes. As a result of dynamic recovery, the flow stress depended on the strain rate through the hyperbolic sine function and on the temperature through an Arrhenius function. The subgrain sizes in the steady state regime were related by simple functions to the flow stress and also to the room temperature hardness. The behavior of type 317 steel is compared with that of type 304 steel which has been the subject of much research.
