Original Abstract

The present study was focused on the high-energy ball milling preparation of the oxide dispersed Mo-10 vol.%La2O3 composite powder by using two high energy ball milling systems, including an attritor mill with horizontally operating rotor and a planetary mill. Microstructural investigations using scanning electron microscopy (SEM) and X-ray powder diffraction (XRD) found out that composite powders with a refined laminated microstructure can be obtained using both milling systems. Under selected milling conditions, Mo-La2O3 powder with better particle size homogeneity and more uniform and dispersed ceramic phase distribution was received in the planetary mill that can be connected with more balanced contribution of breaking and cold welding processes during high energy milling.
