    Ball Milling As A Way To Produce Magnetic And

    Apr 20, 2017 Ball milling (BM) is a well-established technique for producing different materials in powder shape. Dynamical analysis of BM helps to optimize the process through simple but general relations (e.g., definition of an equivalent milling time). Concerning the field of study of magnetocaloric effect (MCE), BM is used in different ways as a single step process (mechanical alloying), as an initial ...
