1. “The grain size of metal sheet influences its formability in two opposing ways. The yield strength of a metal increases as the grain size decreases. So, the formability of a component may decrease if the grain size gets too small. Larger grained metals have better formability, but the roughened surface that results from stretching metal with grain sizes that are too large is unacceptable for many applications. During a recrystallization anneal new grains form in the metal. The final grain size depends on the annealing temperature and annealing time.” As shown in the figure below (1"x1" area under a 50Xmagnification microscope), a cold-rolled metal has been annealed at 550 degrees C for one hour. Calculate the ASTM Grain Size Number for the following condition: image attached
