What is Precision measurements of critical resolved shear stress in CuMn alloys about?
The critical resolved shear stress T&) and the activation volume V(T) of CuMn single crystals were measured in the temperature range from 4 to 450 K for 2.0 C c < 7.6 at.% M 20 K the temperature dependence of 70 and V can be described consistently by the concept of thermally activated dislocation motion. Below about 20 K the curvature of s,(T) changes sign and approximates a finite value for T -+ 0 K. These deviations from ordinary thermally activated glide behaviour are discussed in terms of inertial effects, sample heating and quantum effects like tunneling and zero-point vibrations of dislocation segments. A satisfactory explanation of the new anomaly is possible only by the theory of zero-point vibrations of dislocations.
