Aspects of NdFeB HDDR Powders: Fundamentals and Processing,d the appropriate temperatures and hydrogen pressures are employed during disproportionation and recombination. The detailed nature of the anisotropy mechanism still requires clarification but the presence of an intermediate boride could be the deciding factor and would explain the absence of any anisotropy in the Sm.Fe.N.-H. system.

Bonded Rare Earth Magnets Produced by Hot Pressing,cations; (d) Isotropic bonded magnets can be easily magnetized into various and complex magnetization patterns; and (e) Fully automated production processes lead to more uniform magnetic properties, high precision and repeatability. Some disadvantages of polymer bonded magnets include: (a) Lower mag

Developing Bonded HDDR Magnets for a Slovenian SME,rovided little help for optimising the processing conditions. By combining the substitutions of Pr and Zr in a relatively rare-earth-rich alloy we were able to produce a coercive powder of > 1000 kA/m and have a process which can now be quickly and easily transferred to the factory.

Review on Bonded Magnets,ic impact some examples of current physical and technical questions and possible solutions are discussed. These examples are intended to demonstrate that basic research is necessary on different levels beginning with the understanding of intrinsic magnetic properties on an atomar level, the study of

Aspects of NdFeB HDDR Powders: Fundamentals and Processing,ising feature of the HDDR process in NdFeB (and PrFeB)-type alloys is the development of anisotropy in the Nd.Fe.B phase after recombination of the disproportionated mixture. Early work on this phenomenon reported that alloying additions such as Co and/or Ga were essential in developing the preferre
