Abstract

Uranium-6 wt pct niobium (14 at pct niobium) displays the shape memory effect (SME), where deformation proceeds by twinning and twin rearrangement via boundary migration within the SME regime. In-situ neutron diffraction during deformation suggests that after SME strain is exhausted, deformation proceeds via another twinning mechanism that does not recover to the original parent orientation upon reheating and transformation. Here we show from in-situ tensile and compressive loading and unloading experiments that early post-SME twins partially reverse during unloading, which is evident by rapid texture evolution, and this reversion is responsible for the inelastic portion of the previously reported ~ 2 pct strain recovery.

The rotation for the (010) vs the (100) twin differs by only ~5 deg, too small to be differentiated by the texture data. Therefore, the twin will be henceforth referred to as (010), with the understanding that either it or its reciprocal could be responsible for the observed rotation.[11]

In both the tension and compression curves, there is a lowering of the work hardening rate (WHR), which is often referred to in the literature as a plateau, even though the WHR does not go to zero.
