Mole-Fraction Mn °cc+a+M2N FIG. 11
The calculated isothermal section at 1073K through the Cr-Mn-N phase diagram, showing equilibria with 30 atm N2 gas. The full lines show the calculations, and the dashed lines have been redrawn from the experimental study by Ettmayer et al.(4). The MngN4 phase is stable in the calculated phase diagram, but it was not found experimentally.

The full lines show the calculations, and the dashed lines have been redrawn from the experimental study by Ettmayer et al.<4). The MngN4 and the MnfiN5 phases were suspended from the calculation.
