Mechanical alloying is largely what it sounds like: creating a new alloy by mechanically forcing two or more metal powders together. The forcing is performed by the impact of media in a high energy ball mill. Depending on the metals, mechanical alloying can provide some challenges. One is that the alloy may adhere to the tank surface and media.
Planetary ball mill is a very often used machine for mechanical alloying, especially in Europe. Because very small amount of powder (for example, as little as a few grammes), is required, the machine is suitable for research purposes in the laboratory. The grinding balls in the planetary mills acquire much higher impact energy than is
