  • Grain Size and Its Influence on Materials Properties

    2011-5-16 · 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.
