High-temperature magnetic properties of mechanically alloyed SmCo 5 and YCo5 magnets
The high-temperature coercivity of mechanically alloyed and subsequently annealed RCo5 (R= Sm and Y) is studied. The annealed materials have the hexagonal CaCu5 structure with 2 : 17 (or 1 : 7) regions as a minor phase. High-temperature magnetic measurements show that the coercivities of materials decrease with increasing temperature from room-temperature to 873 K, but that the temperature coef...
متن کاملStructural Characterization and Ordering Transformation of Mechanically Alloyed Nanocrystalline Fe-28Al Powder
The synthesis of nanocrystalline Fe3Al powder by mechanical alloying as well as the structural ordering of the synthesized Fe3Al particles during the subsequent thermal analysis were investigated. Mechanical alloying was performed up to 100 hours using a planetary ball mill apparatus with rotational speed of 300 rpm under argon atmosphere at ambient temperature. The synthesized powders were cha...
