Calorimetric and Morphological Studies of Mechanically Alloyed and Mechanically Disordered Al-50at% Transition Metal Alloy Powders.

Magnetic hysteresis of mechanically alloyed Smâ•fiCo nanocrystalline powders

XANES of Mechanically Alloyed Y-Fe System

We have measured X-ray absorption near edge structure (XANFS) of mechanically alloyed YzFe and YFez system as a fundion of milling time. An amorphous phase is obtained by mechanical alloying for 100 hours in the YzFe system and for 500 hours in the YFez system. In both systems the intensity of Fe Is-4pn transition grows up significantly with increasing the milling time and approaches to that of...

MgB2 superconducting tapes with mechanically alloyed precursor powders as a possible alternative to NbTi

Structural 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...

IN SITU FABRICATION OF Al 2024-Mg2Si COMPOSITE BY SPARK PLASMA SINTERING OF REACTIVE MECHANICALLY ALLOYED POWDER

In situ Al2024- Mg2Si composite was fabricated by spark plasma sintering (SPS) of reactive powder. Reactive powder was obtained from mechanical alloying (MA) of elemental powders. Clad layers of in situ composite were fabricated on Al substrates by spark plasma sintering (SPS). Structural evolution during MA process and after SPS was investigated by X-ray diffractometery (XRD). Scanning electro...
