Analysis of recrystallized volume fractions in uranium using electron backscatter diffraction

Summary Electron backscatter diffraction was used to examine the recrystallization behaviour of warm, clock‐rolled uranium. A new uranium preparation method was developed, resulting in acceptable specimen surface finishes nearly every time, even for as‐rolled specimens. Recrystallized fractions were differentiated from unrecrystallized fractions using differences in the grain average misorientation, a measure of the internal level of misorientation within a grain. This new approach better estimates the recrystallized fraction than hardness measurements, and has the advantage over standard metallographic techniques of providing texture information.
