Die Löslichkeit von Wasserstoff, Deuterium und Stickstoff in Eisen

Thermodynamics of Nitrogen Solubility and AlN Formation in Multi-Component High Mn Steel Melts

“…The selfinteraction parameter of N in liquid iron, e N N and r N N are known to be zero. 12) In the present study, a mixture of N 2 and Ar-10% H 2 gases was used to keep the aimed nitrogen partial pressures and low oxygen level in the melt. The oxygen content was determined as less than 20 mass ppm under this condition and the hydrogen content was calculated to be 2.5-7.5 mass ppm depending on nitrogen partial pressures using the recommended data in JSPS.…”

Determinations of hydrogen in ferrous materials by vacuum extraction at 800 degrees C and by vacuum fusion

“…Data for the solubility of hydrogen in solid iron at elevated temperatures have been reported by several investigators [4,7,16]. These data suggested the possibility of preparing specimens with known and determinable hydrogen con ten ts by rapidly quenching specimens which had been saturated with hydrogen at elevated temperatures.…”

“…The dashed line shows the solubility of hydrogen in iron at various temperatures, as reported in the lit· erature [4,7,16]. portion of a specimen immediately after the quench showed a hydrogen content of 0.00041 percent.…”

“…A comparison of the results of these experiments with the solubility data [4,7,16] is shown in figure 3. Both curves show that the solubility of hydrogen increases with increasing temperature and that there is an abrupt change in solubility in the region of the Aa transformation.…”

LIX. Note on some theoretical discussions of palladium-hydrogen and cognate, systems

“…; while in the neighbourhood of 1400 ° the y-form in turn goes over to the body-centred 3-lattice, with a diminution of approximately 3.8 per cent. in solubility (25). Since solubility, both at Aa and at A 4, is greater in the denser y-lattice, occlusive capacity appears to be determined not by the volume of the lattice, but possibly by its susceptibility to deformation.…”
