1) Hi just checking if the definition of grain size is the average size of grains in a metal expressed as average diameter. if it is not or if there is a more accurate definition could u define it for me.
2) and if the formula N=2n-1 or is it N=2^(n-1)
n being the number of grains per square inch at magnification of 100 diameters.
or if i am completely wrong please tell me.
thank you
