2019-4-3 In summary, studies on ball milling have reported two primary findings: (a) the crystallite size, d, decreases with milling time and continuous milling leads to a minimum grain size, d min, which is a characteristic of each metal; and (b) the lattice strain increases rapidly, reaching a maximum value that coincides with the minimum grain size, d min.
