A method for the determination of the vapour pressure of chromium has been devised by combining Knudsen's effusion method with tracer analysis using Cr-51 of half-life 27.8 days. The vapour pressures determined in the temperature range 1170"-1400Β°C agree with previous work and may be represented by

β¦ Synopsis
The temperature variation of the equilibrium between N2 gas and N-Fe solid solutions has been measured. The results give the rollowing values for the partial molar enthalpy and excess entropy of N-atoms in 7 and I iron:

The free energy difference between the b.c.c. and f.c.c. forms of iron over the temperature range from 500Β°K to 1183Β°K and the excess entropy of f.c.c. iron-manganese alloys at 1450Β°K are computed from activity data for comparison with results obtained from specific heat data. Reasonable agreement i
The temperature variation of the solubility of nitrogen at atmospheric pressure in a series of Fe-MO b.c.c. solid solutions containing 3,4, and 5 at.% MO has been measured in the temperature range 933-1645 K. Deviations from simple regular mixing behavior are seen at high temperatures. Measurements
