• The mean lineal intercept l does not really provide the grain size, but is related to a fundamental size parameter, the grain-boundary area per unit volume, Sv, by the equation

• The most correct way to express the grain size (D) from lineal intercept measurements is:

• Therefore, the grain size (D) of the material of Figure 10.4 is:

10-2
