Thermodynamic activity measurements of iron in Fe–Zr alloys by high temperature mass spectrometry

The thermodynamic activity of Fe in the Fe–Zr alloys respectively for the temperature and composition ranges of T = 1501–1852 K and x Zr = 50–95 at.%, has been measured by the multiple Knudsen effusion cell–mass spectrometric method. The liquidus temperature of the three compositions 56.1, 60.2 and...

Summary:The thermodynamic activity of Fe in the Fe–Zr alloys respectively for the temperature and composition ranges of T = 1501–1852 K and x Zr = 50–95 at.%, has been measured by the multiple Knudsen effusion cell–mass spectrometric method. The liquidus temperature of the three compositions 56.1, 60.2 and 87.2 at.% Zr are determined from the variations of activity and compared with the literature data.
