Analysis of hydrogen in high Mn steel using SIMS-RAE

Abstract

Secondary ion mass spectroscopy (SIMS) is an analytical technique that can be used to characterize the surface and near surface region of solids. One of the advantages of SIMS is the outstanding impurity element detection limits of part per million atomic for most elements. However, SIMS quantification is subject to many effects. Not only the matrix effect of the materials but also the sputtering process will often affect the interpretation of the data [1]. SIMS-Resistive Anode Encoder (RAE) is a powerful tool for mapping the distribution of impurity elements. Hydrogen in high Mn steel was successfully analysed using SIMS-RAE as similar as previous studies of boron analysis in iron and steels using SIMS-RAE [2-3].
