Bulk nanocomposite magnets produced by dynamic shock compaction
(Georgia Institute of Technology, 2004-07-15)
Exchange-coupled R₂Fe₁₄B/α -Fe (R = Nd or Pr) nanocomposite bulk magnets with nearly full density have been successfully produced by shock compaction of melt-spun powders. X-ray diffraction and transmission electronic ...
Interface structures in FePt/Fe₃Pt hard-soft exchange-coupled magnetic nanocomposites
(Georgia Institute of Technology, 2003-05-26)
Self-assembly of FePt and Fe₃O₄ nanoparticles of different sizes led to various FePt–Fe₃O₄ nanocomposites. Annealing the composite under reducing atmosphere at 650 and 700 °C induced magnetically hard FePt phase and ...
Grain size dependence of magnetic properties in shock synthesized bulk Pr₂Fe₁₄B/α-Fe nanocomposites
(Georgia Institute of Technology, 2004-09-15)
The structural and magnetic properties of the melt-spun Pr₂Fe₁₄B/α-Fe nanocomposite powders consolidated via shock-wave compression and subjected to postshock thermal treatment were investigated. Shock compression results ...
Characterization of nanometer-scale defects in metallic glasses by quantitative high-resolution transmission electron microscopy
(Georgia Institute of Technology, 2002-03-25)
Although defects can have a significant effect on the properties of amorphous materials, in many cases these defects are poorly characterized and understood. This is at least partly due to the difficulty of imaging ...
