Structural and phase evolution in mechanically alloyed calcium copper titanate dielectrics

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...

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...

Degradation of TATP, TNT, and RDX Using Mechanically Alloyed Metals

Deformation Mechanisms in Pure and Alloyed Copper Films

In this work, the evolution of microstructure and the thermo-mechanical behavior of co pper and dilute copper alloy thin films was investigated. 0.3 to 2.0 μm thick film s were deposited by magnetron sputtering under ultra high vacuum conditions onto diffusion-barrier coated silicon substrates and subjected to wafer curvature measurements. Pure copper films annealed in ultra high vacuum exhibit...
