Correlation between energy transfer and end products in mechanical alloying process

Abstract

The energy transfer events in the Mechanical Alloying (MA) process are essentially due to attrition and to collisions between the milling tools and the milled powder. The Pd{sub 8}0Si{sub 2}0 composition was investigated in different milling conditions using both planetary (FRITSCH) and vibratory (SPEX) apparatuses. X-ray diffraction and differential scanning calorimetry measurements were used in monitoring the various Solid State Reactions (SSR) taking place in the different milling conditions. The paths of the SSR essentially go towards two distinct end products: a fully amorphous phase or an intermetallic compound depending on the conditions of energy transfer. The results were explained on the basis of attrition or collision events becoming predominant in given milling conditions.
