Metastable Soft Magnetic Materials Produced by Mechanical Alloying: Analysis Using an Equivalent Time Approach

Description

Mechanical alloying, a ball milling technique where heterogeneous starting powders are homogenized and alloyed, has become a versatile technique for the production of metastable microstructures: nanocrystalline and/or amorphous alloys, supersaturated solid solutions, etc. Ball milling is affected by many experimental parameters and the analysis of the dynamics of milling is needed to compare different experiments and to optimize time and costs. In this work, a short overview on the microstructural techniques used to characterize the powder is supplied. The soft magnetic properties of mechanically alloyed powders are also described, as well as the magnetocaloric response of these systems.
