Precipitate characterisation of an advanced high-strength low-alloy (HSLA) steel using atom probe tomography

The microstructure of an advanced high-strength low-alloy steel containing nanoscale Ti0.98Mo0.02C0.6 carbides formed along gamma/alpha interface was characterised using atom probe tomography. The average radius of particles was 2 +/- 0.5 nm. In addition, the formation of C19Cr7Mo2.1 particles with average radius of 1.5 +/- 0.3 nm was also observed. (c) 2007 Acta Materialia Inc.
