OSTI ID:6369711
This investigation examined the effect of varying strain upon the spacing of dislocations in subgrain boundaries in Type 304 stainless steel torsionally deformed at 1138/sup 0/K (0.63 T/sub m/). It was found that the spacing, d, decreased with strain during both transient (primary) and steady-state (secondary) creep. It also appeared that the average subgrain size, lambda, decreased with strain during steady state. The results suggested that these two features may not strongly influence creep strength.
