On the origin of an anomalous thermal arrest within the β range in uranium

Abstract

Duwez and Butcher and Minty observed during quenching experiments of uranium samples an anomalous thermal arrest (ATA) between the thermal arrests corresponding to the y --f /I and ,4 -+ iy phase transformations. This ATA did not correspond to any established phase change in uranium. Measurements of other physical properties at high temperatures 3-s) failed to show any changes or ~scontinuities which correspond to a phase change associated with the ATA.
