The background temperature of milling bodies and processed material is analyzed using calorimetric measures and methods of melting of reference substances during mechanical alloying of powders in planetary ball mill. It is shown that estimation of the background temperature using the calorimetric method provides more precise measurements compared to the melting method of reference …

In order to understand the mechanical alloying (MA) process in a planetary ball mill (PBM), the kinetics of a ball during milling have been analysed and the calculated ball trajectory is compared with in-situ observations of ball movement. Three different milling modes are deduced from the modelling.
