Rapid consolidation method for preparing bulk metastable iron-rich materials
Abstract
Interstitially modified compounds of rare earth element-containing, iron-rich compounds may be synthesized with a ThMn12 tetragonal crystal structure such that the compounds have useful permanent magnet properties. It is difficult to consolidate particles of the compounds into a bulk shape without altering the composition and magnetic properties of the metastable material. A combination of thermal analysis and crystal structure analysis of each compound may be used to establish heating and consolidation parameters for sintering of the particles into useful magnet shapes.
