Assume that 16 grains per square inch are counted in a micrograph taken at 250X.What is the ASTM number for grain size?
To provide some perspective on the dimensions of atomic defects, consider a metal
specimen that has a dislocation density of 104 mm-2. Suppose that all the
dislocations in 1000 mm3 (1 cm3) were somehow removed and linked end to end.
How far (in miles) would this chain extend? Now suppose that the density is
increased to 1010 mm-2 by cold working. What would be the chain length of
dislocations in 1000 mm3 of material?
In an measurement with 100× magnification factor
on metal specimen, 65 grains per square inch are
observed. Determine the ASTM grain size number
of the specimen.
