Milled Material - an overview | ScienceDirect Topics

Trying to relate the d min obtained during milling to the physical and material properties of the material being milled, it is noted that it decreases with an increase in the melting temperature of the metal (Eckert et al., 1992a).This trend is amply clear in the case of metals with close-packed structures. Figure 3.6 shows a plot for metals with a face centered cubic (fcc) structure and a ...
