Webnanocomposites and pure carbon sample were prepared by high-energy mechanical milling (HEMM, 8000 M Mixer/Mill, SPEX, USA) under an argon atmosphere for 8 h. The metal:carbon black weight ratio was set to 7:3. In the case of SnSb/C, the Sn:Sb was 1:1 by molar ratio. The Sn and Sb bulk samples were respectively prepared Web12 de out. de 2024 · However, several studies are related to the use of the high-energy mechanical milling (HEMM) also known as mechanical alloying (MA). MA technology has been used almost 60 years as an alternative processing of various materials such as metal powder alloys, composites, intermetallic compounds, casting alloys, and ceramics [8, …
