1.. IntroductionMechanical alloying (MA) is a versatile route of solid state synthesis of nanometric novel materials with metastable microstructure and composition [1].It is known that high energy ball milling in a planetary mill leads to MA of the constituent powders through a process involving repeated deformation, fragmentation and cold welding [1].
Section snippets Experimental. Mechanical milling was performed by using a planetary ball mill (PBM) under various experimental conditions. Copper powder (% purity, median particle size x 50 = 45 μm, Aldrich chemistry) was used as shown in Fig. 1. Mechanical alloying (MA) was carried out at two types of rotation speeds: low (10, 50, and 100 rpm) and high (300, 500, and 700 rpm).
The Planetary Micro Mill PULVERISETTE 7 premium line with 2 grinding stations is designed for a broad range of applications and ideally suited for lossfree grinding down to a final fineness of 100 nm of hard, mediumhard and brittle materials.
