Grain Size and Its Influence on Materials Properties

Grain size has a measurable effect on most mechanical properties. For exam-ple, at room temperature, hardness, yield strength, tensile strength, fatigue strength and impact strength all increase with decreasing grain size. Machinability is also affected; rough machining favors coarse grain size while finish machining favors fine grain size.Grain Size DistributionsIn measuring the grain size of this specimen, we could determine the grain size of this one very large "rogue" grain by Methods E 930 and the rest oi the grains using Test Methods E 112.
