However, the fundamentals of change in particle morphology of ductile metal powder during high energy milling is same for all the devices and can be attributed to a combination of phases, i.e. micro-forging, fracture, agglomeration and de-agglomeration, all of them can take place simultaneously in a mill [4]. It is therefore important that periodic samples are drawn at different stages of a ...
