An anomaly in the heat capacity of chromium at 38·5°c

Abstract
Several properties of pure chromium metal show an anomalous temperature dependence in a broad temperature region below 50°c (Sully 1954); the temperature coefficients of some (e.g. Young's modulus, expansivity) undergo an abrupt reversal of sign at about 38°c. Different interpretations of the phenomena have been discussed (Pursey 1958, Neumann and Stevens 1959), but none seems to have been fully substantiated.
