Mechanical alloying/milling technique is characterized by the repeated welding and fracturing of powder particles in a high-energy ball mill which often results in excessive cold welding and agglomeration of ductile particles To achieve the critical balance between cold welding and fracturing the surface of the deforming particles is modified by introducing a suitable organic material Mechanical alloying and reactive milling in a high energy 10/06/2009 Note that the models proposed earlier for mechanical alloying in planetary mill ignored rolling ball motion as affecting the refinement or phase changes in the powder being processed

Mechanical Alloying (MA)

Abstract The formation of quaternary 76Ni17Fe5Cu2Cr (wt %) alloy by mechanical alloying is investigated The elemental powders of Ni Fe Cu and Cr where milled in argon atmosphere in a planetary ball mill for time up to 20 h Formation of the alloy was checked by X-ray diffraction studies
