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 ...
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 ...
Amorphization and ultrafine-scale recrystallization in shear bands formed in shock-consolidated Pr₂Fe₁₄B/α -Fe nanocomposite magnets
(Georgia Institute of Technology, 2004-09-20)
Amorphization and ultrafine-scale recrystallization within shear bands formed in shock-consolidated Pr₂Fe₁₄B/α -Fe nanocomposite magnetic powder compacts have been observed using transmission electron microscopy. The shear ...
