A surfactant-assisted high energy ball milling technique to produce colloidal nanoparticles and nanocrystalline flakes in Mn-Al alloys

Popis výsledku v původním jazyce

We herein exploit the advantages of surfactant assisted-high energy ball milling (SA-HEBM) for the processing of Mn-Al alloy. In this method, a combination of two surfactants, such as oleic acid and oleylamine, was used along with a solvent, n-heptane, during milling. The use of the SA-HEBM process yielded two different products: a sediment powder consisting of sub-micron sized Mn-Al flakes and a suspension in the milling medium (colloid) containing Mn-Al nanoparticles. The colloid consisted of Mn-Al nanocrystalline particles (5-16 nm) having a lamellar morphology with an average thickness of 1.5 nm and length of 16 nm. Magnetic measurements of these colloidal nanoparticles demonstrated an almost non-magnetic behavior at 300 K. The Mn-Al sediment powders obtained with the SA-HEBM process at regular milling time intervals were investigated for their structural and magnetic performance and also compared with the corresponding powders obtained from the conventional HEBM process. The phase
