Modeling of impact energy generated by free falling ball / Salina Budin, Aznifa Mahyam Zaharudin and Sugeng Priyanto

As a common practice in Mechanical Alloying (MA), the mixture of the work materials to be alloyed is placed in a container together with relevant milling medium. The vial and the charge materials are then moved in such a manner to create kinetic energy on the charge materials in the vial. Upon the c...
