摘要
In a previous work of ours on molybdenum single crystals, we have assumed that an unsaturated chemical exchange bond exists between the impure atoms and the dislocation centre dangling ones, and using the Morse function, we have obtained an important resuit, that is, the CRSS (critical resolved shear stress) of the BCC metal may be expressed by the parameters of the Morse function, and the temperature dependence of it seems to follow approximately an exponential law,
