High temperature tensile testing of modified 9Cr–1Mo after irradiation with high energy protons

摘要: Abstract This study examines the effect of tensile test temperatures ranging from 50 to 600 °C on properties a modified 9Cr–1Mo ferritic steel after high energy proton irradiation at about 35–67 doses 1 3 dpa and 9 dpa. For specimens irradiated between dpa, it was observed that yield strength ultimate decreased monotonically as function temperature, whereas uniform elongation (UE) remained approximately 1% for up 250 then increased including 500 °C. At °C, UE be less than values 400 material tested 400–600 greater unirradiated same temperatures. Tensile tests followed similar trends.
