Mechanical Alloying (DSM) - Union Process

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.
