a) Using the intercept method- determine the average grain size- in mi.docx

  1. a) Using the intercept method, determine the average grain size, in millimeters, of the specimen whose microstructure is shown in Figure 4.14( b ); use at least seven straight-line segments. (b) Estimate the ASTM grain size number for this material. Solution Below is shown the photomicrograph of Figure 4.14( b ), on which seven straight line segments, each of which is 60 mm long has been constructed; these lines are labeled
