2021-10-13  Commercial powders of pure magnesium were processed by high-energy ball milling. The microstructural and morphological evolution of the powders was studied using scanning electron microscopy (SEM), energy dispersive spectrometry (EDX) and X-ray diffraction (XRD). From the results obtained, it was determined that the ball size is the most influential milling parameter.

Preparation and properties of lead-free copper matrix ...

After ball milling, the diffraction peak width increases due to the grain refinement of the mixed powder, as shown in Fig. 7(2/4). Ball milling makes the lattice distortion of CuSn10 alloy produce dislocation and other defects. On the one hand, Bi or FeS solid solution in the CuSn10 alloy causes the diffraction peak of the CuSn10 alloy to decrease.

Enhancement of Characteristics of Nitrogen-Doped

2020-9-10  Beside ratio of the raw material, the ball milling conditions were also studied as summarized in Table 1. For practical purposes, effect of short milling time, at 500 rpm speed, was studied here. Xue et al. (2015) used the 500 rpm milling speed for 48 h, which is practically too long. A much shorter milling time (30 min) has been chosen here.
