On the Solubility of Boron in High-Purity Alpha-Iron

Abstract

Damping tests at 1 c/s and dilatometric measurements of the α–γ transition temperature have been carried out on high-purity iron (99·9985%) and its dilute alloys with boron. Confirmation has been obtained of the hypothesis previously advanced that boron does not dissolve interstitially in alpha-iron when the metal is very pure and, more generally, that the available data for boron solubility are dependent on the content of impurities in the iron used.
