Abstract
The annealing behaviour of type 316 stainless steel prestrained with various degrees 10-30%, after solution treatment was investigated by using quantitative metallographic techniques. With increasing degree of prestraining slip bands are heavily formed and their densities gradually decrease as annealing time elapses. Fine M_(23)C_6 type complex carbides are found to precipitate along grain boundaries, slip bands and twin boundaries and to affect the restraint of recrystallized grain boundary movement. The average values of grain size during annealing are shown to increase as prestraining percentage decreases. In particular, grains tend to be coarsened in the case of prestraining of less than 10%. The effects of prestraining on the increase in hardness appear to be considerable as compared to those of annealing temperature, showing that Vickers hardness values increase with increasing prestraining percentage. For a given prestraining condition changes in hardness with respect to grain size are obtained to be in good agreement with the Hall-Petch type relation irrespective of annealing temperature.
