Segregation of boron at prior austenite grain boundaries in a quenched martensitic steel studied by atom probe tomography
The distribution of B and other alloying elements (C, Cr, Mo) at prior austenite grain boundaries (PAGBs) and in the matrix was quantified by atom probe tomography in a quenched martensitic steel. B and Mo were observed to be segregated only at PAGBs and to be absent at martensite martensite boundaries. C is segregated both at PAGBs and at martensite-martensite boundaries, whereas Cr is homogeneously distributed in the probed volume. Our results indicate that B undergoes a non-equilibrium segregation. (C) 2014 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved
