Influence of Mechanical Milling and Heat Treatment
2021-4-4 Abstract— We have studied the influence of high-energy treatments on changes in the morphology, structure, phase composition, and (as a consequence) hardness of BrA 10 (DIN CuAl10Fe3Mn2) bronze powder particles. It has been shown for the first time that, independent of energy delivery rate during mechanical treatment of the powder, after the delivery of a given amount of
