Effect of Chromium on Nitrogen Solubility in Liquid Fe–Cr Alloys Containing 30 mass% Cr

Thermodynamic Interaction between Chromium and Titanium in Liquid Fe–Cr Alloys Containing 30 mass% Cr

“…Detailed descriptions of experimental apparatus and procedure are available in author's recent studies on Fe-Ti-N, Fe-Ti-Al-N and Fe-Cr-N systems. [12][13][14] Five hundred grams of high purity electrolytic iron contained in an Al 2 (Received on June 22, 2010; accepted on July 6, 2010 ) Thermodynamic interaction of chromium on titanium in liquid Fe-Cr alloys was studied by measuring the effect of chromium on the solubility product of TiN in liquid Fe-Cr-Ti-N alloys by the metal-nitride-gas equilibration technique in the temperature range from 1 873 to 1 973 K. Titanium nitride formed in the melt was identified as a pure solid stoichiometric TiN. As the chromium content increases in the melt saturated with TiN, the critical nitrogen solubility increases significantly, while the titanium solubility decreases.…”

“…In author's previous studies, [12][13][14] the detailed procedure for chemical analysis is available. The nitrogen and oxygen contents in the metal sample were measured by the inert gas fusion-infrared absorptiometry technique with an accuracy of Ϯ1 mass ppm.…”

“…[3][4][5][6][7] As well, some studies have been conducted for ternary Fe-Cr-Ni system. [8][9][10] However, a few studies have been undertaken for Fe-Cr-Ni-Mo system.…”

Thermodynamic Interaction between Chromium and Aluminum in Liquid Fe–Cr Alloys Containing 26 mass% Cr

“…Detailed descriptions of experimental apparatus and procedure are available in author's recent studies on Fe-Al-N, Fe-Cr-N and Fe-Cr-Ti-N systems. 5,6,8) Five hundred grams of high purity electrolytic iron contained in an Al 2 O 3 crucible (OD: 56 mm, ID: 50 mm, H: 96 mm) was melted in the temperature range from 1 873 to 1 973 K. The melt temperature was monitored by a Pt/Pt-13mass%Rh thermocouple sheathed with an 8 mm OD alumina tube immersed in the melt. Previous studies confirmed that no significant noise was detected.…”

“…Also, there is no information about the temperature effect on this important parameter value. In author's recent studies, 5,6) thermodynamics of Fe-Al-N and Fe-Cr-N melts were studied as a function of temperature using the metal-nitride-gas and the metal-gas equilibration techniques, respectively, as summarized in Table 2.…”
