Abstract

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 collisions of the charge materials against each other as well as against the wall of the vial, kinetic energy is then converted into impact energy. This impact energy is than absorbed by the work materials for repeatedly flattened, cold welded, fractured and rewelded, which is an important mechanisms in MA. Since MA process utilizes energy generated by impact, it is important to understand the way on how kinetic energy of charge materials is transferred into impact energy. This report present a model of energy conversion and impact energy generation during the collision based on free falling experiment, which is a closest resemblance to the direct collision between ball and inner wall of the vial.
