Ductility in bending of molybdenum alloys irradiated between 425 and 1000/sup 0/C

Conference ·
OSTI ID:6259263

Molybdenum and the alloys Mo--0.5% Ti and TZM were irradiated at four temperatures between 425 and 1000/sup 0/C, to a displacement level of 11 dpa at a fluence of 2.5 x 10/sup 26/ n m /sup -2/ (> 0.1 MeV). Vacuum bend tests at elevated temperatures showed the ductile-to-brittle transition temperature (DBTT) to be above room temperature for all irradiation temperatures. Irradiation at 585/sup 0/C produced the highest DBTT, 550 to 700/sup 0/C. Differences among the three materials were minor.
