Abstract
The MAGNEQUENCH process for making high energy product (> 10 MG•Oe) permanent magnet alloys of Nd2Fe14B has been described. To advance further the commercial application of these alloys, a better understanding of the microstructure and crystallography is required.The crystal system and unit cell parameters can be determined from the angular positions of the x-ray diffraction peaks, provided the data have been collected with a 2θ accuracy error of <0,02°. Computer based methods are available for handling the large number of calculations required. This paper describes the experimental problems encountered and solved during the determination of the cell parameters for this alloy.
