Analysis of the Background Temperature During the Mechanical Alloying of Metal Powders in the Planetary Ball Mill

Resumo

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 substances. The dependence of background temperature change on mechanical alloying time, vial filling coefficient, mixture content of processed materials, rotation velocity of carrier, and processing atmosphere is presented.
