With the increase of B con-tent from 0.0005 to 0.0029 wt-%, the volume fraction of the austenite decreases atconstant intercritical annealing temperature, the hardenability of the austenite inc-reases remarkably, as well as the martensite content and the sensitivity of tensile pro-perties to cooling rate decrease. It was observed by using isotopic tracing autora-diography that after intercritical annealing, the B atoms segragate at the grainboundaries of austenite produced during normalization, no evidence of the migrationof B atoms to α/γ interfaces was found.
