High Temperature Texturing of Engineered Materials in a Magnetic Field

Abstract

The primary objective of this proposal is to investigate the effect of high field/temperature in the development of texture (preferred orientation) in magnetic materials. Highly textured permanent magnet materials of Ne2Fe14B have been produced using the facility constructed within the first part of the ARO support. Other materials systems including: FePd, Terfenol-D, steel and Zink material have also been processed and a highly oriented microstructure has been obtained in these materials. The success in texturing Zn-1.1% Al diamagnetic material shows that the new processing technique can also be applied to nonmagnetic materials. A new initiative in orienting nano-tube in magnetic field resulted in a huge success. These studies were carried mostly in a newly constructed high temperature furnaces funded by ARO. This facility includes two high temperature furnaces (1250 deg C and 1600 deg C) in the bore of a 20 inch resistive magnet capable of producing a uniform high magnetic field of 20 Tesla. These studies will also be carried out in the core of a 9 Tesla superconducting magnet.
