RETENTION OF URANIUM BETA PHASE
Technical Report
·
OSTI ID:4162193
A study was carried out on the retention and metastability of the beta phase in dilute uranium base alloys. It is anticipated that, because of their greater strengths, the beta phase alloys will possess greater resistance to swelling during irradiation than either the alpha phase or gamma phase uranium base alloys. Among the alloys investigated, the U-0.3 wt.% Cr binary and the U- 0.3 wt.% Cr-0.3 wt.% Nb or Mo ternary alloys exhibited the best retention and stability properties. Calculations indicate that if neutron induced phase reversion occurs, upwards of 90% beta would be retained in these alloys during irradiation at 400 to 500 deg C and fission rates of about 10/sup 14/ fissions/cm/ sup 3/sec.
