HYDROGEN AND FLAKES IN STEEL (SELECTED PART)
Abstract
Studies were made to determine the solubility of H in Fe. It was found that the solubility of H is proportional to the square root of its pressure and that it rises with temperature. AlphaFe is transformed into gamma-Fe, and also at the melting point of delta-Fe, the solubility of H increases abruptly. When Fe is transformed from the gamma phase to the delta phase the solubility decreases somewhat. The effect of temperature and pressure on the solubility of H in liquid Fe was determined. For liquid Fe, the solubility of H is proportional to the square root of its pressure. Inclusions normally found in steel or admixtures used for alloying steel alter the phasetransformation temperature by expanding or contracting the gamma-Fe region. At room temperature the coefficient of H diffusion in the gamma-Fe lattice is almost 10,000 times less than in the alpha-Fe lattice. (Author)
