Miniature Charpy Impact Test Results for the Irradiated Ferritic Alloys HT-9 and Modified 9Cr-1Mo

摘要

Impact tests of irradiated Charpy specimens made of ferritic alloys were conducted at temperatures from -65 exp 0 C to 250 exp 0 C. The specimens involve four different material stocks, namely, HT-9 base metal, HT-9 weld metal, HT-9 heat-affected-zone (HAZ) and modified 9Cr-1Mo base metal. The specimens were irradiated in EBR-II to a peak exposure of approximately 13 dpa at temperatures of 390, 450, 500 and 550 exp 0 C. Specimens made of unirradiated HT-9 base metal and modified 9Cr-1Mo base metal were also tested. (ERA citation 08:051193)
