The logarithmic decrements of 2Cr13 steel at room temperature have been determined from the free decay curves of cantilever-beam specimens of which the heat treatment conditions are given. It is found that the logarithmic decrements are not constant for each specimen and related to the stress level of the specimens. The curves of damping versus stress are plotted and the damping exponents are obtained by using regression analysis. The method as mentioned in this paper can be considered as one of the material...
