Given that the grain size in a solid solution is determined according to the following expression: NM = 2*-1 where N is the average number of grains per square inch at a magnification of M, and n is the ASTM grain size number. Carry out the following: Determine the ASTM grain size if 30 grains per square inch are measured at a magnificatic 100X. i. ii. Calculate the number of grains per square inch at a magnification of 75X.
