(a) From the plot of yield strength versus (grain diameter)–1/2
(a) From the plot of yield strength versus (grain diameter)â1/2 for a 70 Cuâ30 Zn cartridge brass, Figure, determine values for the constants s0 and ky in Equation 7.7.
(b) Now predict the yield strength of this alloy when the average grain diameter is 1.0 x 10-3 mm.
