From Equation 8.19, if the logarithm of is plotted versus the logarithm of s, then a straight line should result, the slope of which is the stress exponent n. Using Figure 8.31, determine the value of n for the S-590 alloy at 925째C, and for the initial (i.e., lower-temperature) straight line segments at each of 650째C, 730째C, and 815째C.
