The three elastic constants of tantalum, tungsten and molybdenum
have been measured in the temperature range between 4.2 and 300 K. The
directly measured quantities C and —(C^-C. J for molybdenum and the
computed bulk moduli of all three 'elements show an anomalous temperature
dependence. These data along with published results for other metals
generally show a difference in temperature dependence of the bulk modulus
between 3d and 4d-5d metals. Overlap contributions to the elastic constants
are found to favor an antiferromagnetic ordering. The Debye
characteristic temperatures calculated from elastic constants are found
to be in substantial agreement with results obtained from calorimetry.
