Abstract: HallePetch relationship was investigated for austenitic stainless steels with either 0.3 wt% C or N. It was found that HallePetch slope was higher for the nitrogen-containing steel, which implied that higher stress was required to activate the dislocation source in adjacent grains. It was suggested that the nitrogen in the steel generated slip planarity which hindered the cross-slip at the grain boundaries and delayed the activation of the dislocation source.
