Recrystallization and grain growth in high purity austenitic stainless steels
After cold deformation and subsequent annealing, recrystallized grain sizes of austenitic stainless steels decrease with decreasing carbon concentrations down to 15 mu g/g. This is due to an increase of martensitic transformation during cold work. One can therefore achieve very fine grains from ther...

Summary: | After cold deformation and subsequent annealing, recrystallized grain sizes of austenitic stainless steels decrease with decreasing carbon concentrations down to 15 mu g/g. This is due to an increase of martensitic transformation during cold work. One can therefore achieve very fine grains from thermomechanical treatments by improving the purity of the alloys. By contrast, for carbon concentrations < 15 mu g/g, grain growth kinetics are increased markedly, associated to an increase of grain boundary mobility. This leads to relatively coarse recrystallized grains. Materials include 304, 304L, and high purity 18Cr-12Ni steels. |
