Abstract

The co-precipitation of Cu, M2C (where M is any combination of Cr, Mo or Ti) and austenite (face-centered cubic) is characterized for 5 h isochronal aging times by synchrotron X-ray diffraction and three-dimensional atom-probe tomography for a high-strength low-carbon steel, BlastAlloy 160. High number densities, ∼1023 m-3, of co-located Cu and M2C precipitates were observed. Only small austenite volume percentages (<2.1%) were measured after aging at temperatures up to 625 °C for 5 h.
