Dimensional stability, annealing stabilization, and residual stress analysis of alpha-phase-extruded uranium-2.4 weight percent niobium alloy

Creators

Description

The structural use of alpha-extruded uranium-2.4 wt % niobium (U-2.4Nb) alloy rod was hampered by dimensional instability of the alloy. To develop an understanding of (and a solution to) the problem, the metastable state of the as-extruded and heat-treated alloy was studied with regard to its susceptibility to creep and cracking, its retention of residual stresses, and its dimensional stability. An annealing treatment of 6000C for 30 minutes stabilized the structure and reduced residual stresses and improved dimensional stability. 12 figures, 2 tables
