The conventional and in situ transmission electron microscopy imaging of quenched 1.5 pct Cu steel revealed the presence of Cu phases even before aging, which did not disappear after typical aging times. The formation of 9R precipitates was observed after 15 minutes of heating, becoming more noticeable with longer processing times. Further analysis is needed to understand the precipitation mechanisms in carbon steels, especially due to the inevitable increase in Cu content in steel ingots.
The conventional and in situ transmission electron microscopy imaging of quenched 1.5 pct Cu steel has shown that Cu phases are present even before aging and do not disappear after typical aging times. The 9R precipitates appear after 15 minutes of heating, but they are more noticeable after longer processing times. This suggests that the precipitation mechanisms in carbon steels deserve further analysis, especially because of the inevitable increase in the Cu content in the steel ingots.
