Calculated fraction of FCC Copper precipitates and Copper atoms in the solid solution in 18CrNiMo7-6 carburizing steel with different heat treatment conditions.

	FCC Cu	Cu in solid solution
1.5% Cu, aged at 500°C for 21600 s	0.564	0.436
1.5% Cu, aged at 500°C for 10000 s	0.459	0.541
1.0% Cu, aged at 480°C for 14400 s	0.282	0.718
1.0% Cu, aged at 480°C for 3000 s	0.173	0.827

Can be inaccurate as coherent BCC Cu precipitates are expected.
