摘要: The effects of neutron irradiation and hydrogen on the ductile- brittle transition temperatures (DBTTs) unalloyed vanadium V-Cr-Ti alloys were determined from Charpy-impact tests 1/3 ASTM standard size specimens impact 3-mm diameter discs. conducted containing <30 appm 600-1200 after to 28-46 dpa at 420, 520, 600C. DBTTs minimum (< {minus}220{degree}C) for V-(105)Ti under V-4-Cr-4Ti alloy with hydrogen. effect in was raise by 100--150{degree}C. V-(1-5)Ti irradiation.
