Phase analysis of powder. Figure 1 shows the XRD patterns of the atomized and ball-milled powders for processing times in the range of 2–96 h. Ni as a matrix, Y 2 O 3 as an oxide, Ni 5 Y and Al 2 Ni 6 Y 3 were identified as the intermetallic phases. In the case of atomized powder, which is a raw powder, Ni 5 Y and Al 2 Ni 6 Y intermetallic …
Ball mills are the most common grinding machine employed in the mining industry. Grinding occurs in a single stage, or multiple stages. Multiple stages may include a rod mill followed by a ball mill (two stage circuit), or a semi-autogenous grinding (SAG) mill followed by a ball mill (two stage circuit).
