Research Themes +
Energy Technologies Area (ETA) researchers are continually building on the strong scientific foundation we have developed over the past 50 years. We address the world’s most pressing climate challenges by bringing to market energy-efficient innovations across the buildings, transportation, and industrial sectors. ETA is at the forefront of developing better batteries for electric vehicles; improving the country's aging electrical grid and innovating distributed energy and storage solutions; developing grid-interactive, efficient buildings; and providing the most comprehensive market and data analysis worldwide for renewable technologies like wind and solar.
Strategic Initiatives +
The Energy Technologies Area (ETA) Strategic Plan is the guiding force for our research and development for the next ten years. It clearly charts a path toward clean-energy solutions and focuses on five detailed Strategic Initiatives. The Plan provides an in-depth look at how ETA is accelerating research to provide affordable, clean energy to all while accomplishing deep, economy-wide decarbonization, looking to avoid a rise in global average temperature while simultaneously developing solutions to increase humanity's resilience to extreme weather volatility.

Abstract

One successful additive to Fe‐Nd‐B magnets has been Al, which enhances the iHc significantly, even for a 2 at. % (0.8 wt. %) addition. However, in these magnets it is not clear whether Al partitions into the Re2Fe14B phase, the grain boundary phase, or to the interphase interfaces. The main problem, in this case, is the detection of such small quantities in the microstructure. To overcome this “detectability” problem, magnets with 3.9 wt. % of Al have been prepared by the standard sintering route. These magnets exhibit higher iHc compared to the 0.8 wt. % magnet. The results of magnetic, structural, microstructural and microanalytical examination will be reported in this paper. It is hoped that this will clarify unambiguously the question of Al partitioning. © 1988, American Institute of Physics. All rights reserved.
