The three elastic constants C/sub 44/, 1/2(C/sub 11/-C/sub 12/) and 1/ 2(C/sub C/sub 12/ + 2C/sub 44/) were directiy measured for silver and gold in the temperature range 4.2 and 300 deg K. The various contributions to the values of the 0 deg K constants are analyzed in terms of a simple model which quite successfully describes copper. It is concluded that such a model is unsatisfactcry when applied to the heavier noble metals because these appear to have large noncentral forces contributing to their constants. Combined with pressure data the present results show the elastic constants to be explicit functions of temperature. The Debye characteristic temperatures calculated from the 0 deg K elastic constants are shown to be in substantial agreement with the results from calorimetry. (auth.)
