Abstract
Internal friction of cold worked and hydrogen charged molybdenum was measured from 90 to 400K at about 800Hz. After cold work only the α peak was observed at 120K. When hydrogen was charged, the β peak was observed at about 380 ~ 400K in the first run, but in the second run this peak shifted to lower temperature around 300K. The α peak was suppressed and the β peak showed a maximum when hydrogen charging time increased. These behaviors were interpreted by Igata's model.
