✦ Synopsis
Jr.(l) points out the interesting and quite significant fact that most data on the dependence of yield stress on grain size can be equally well represented as straight lines in plots of a, vs. D-l, D-1/2, or also P1/3 (D = grain diameter).
The fact that apparently on a plot of uV vs. D-1/3 the lines for
