Grain Size and Its Influence on Materials Properties

with decreasing grain size. Machinability is also affected; rough machining favors coarse grain size while finish machining favors fine grain size. The effect of grain size is greatest on properties that are related to the early stages of deforma-tion. Thus, for example, yield stress is more dependent on grain size than ten-sile strength [2, 3].
