Hydrogen embrittlement in high purity iron single crystals
Abstract. High purity iron single crystals with various orientations (resistivity ratio, 3700; diameter, 0.4 mm) were tensile tested with and without simultaneous hydrogen charging. The strain rate and the test temperature were varied widely. Hydrogen embrittlement is observed regardless of hydrogen-induced hardening or softening.
THE PREPARATION AND PROPERTIES OF HIGH-PURITY IRON
AbstractThe methods available for producing high-purity iron can be classified broadly as chemical, electrochemical, and metallurgical. Of these, chemical and metallurgical methods have been used most extensively in the past.
