Ion Microprobe Mass Analysis of Boron in Steel

Abstract

Ion microprobe mass analyzer has been applied to analysis of boron in high strength steels. It is proved that the analytical technique has sufficient sensitivity and resolution to determine the distribution of boron in precise correspondence with metallogrophic microstructure. It is also shown that quantitative analysis of bolon in solid solution is possible, and that the effect of nitrogen on the amount of solute boron can be detected.
