Abstract

The evaluation of the tempering response of an ultra-high-strength, high-toughness (UHSHT) steel revealed that samples austenitized at 900 °C and tempered for 4 and 8 hours at 485 °C had similar yield strengths but a ∼50 pct increase in fracture toughness for the 8-hour temper. The results of our investigations of microstructural origins of this difference, using the nanometric scale resolution of the three-dimensional atom probe (3DAP) suggest that nanoscale strengthening precipitates, essentially carbides and intermetallic clusters (containing primarily Cr and Mo atoms), are present in both samples. The chemical compositions of the particles in the two samples were found to be similar, but clear evidence of differences in physical attributes of the precipitates, such as particle size, morphology, and interparticle spacing, are seen.

More quantitative analysis on the coarser particles might be possible by the use of extraction replicas, but that is beyond the scope of the present work, which focuses on features amenable to investigation by atom probe.
