Abstract
A method of processing polycrystalline material by performing multi-axis crystal alignment utilizing anisotropies in the crystalline structure including the step of providing a polycrystalline material in a fluid suspension or malleable form having a magnetic moment. An external force to which the material is reactive is applied to align the individual crystals along a first axis. A magnetic field is applied to orient the magnetic moment of the crystals along a second axis, transverse to the first axis. The crystalline material may have a magnetic moment associated with a rare earth element of the material.
