High Energy Ball Mill Processing

Materials Science Forum, 2003
The technique named mechanical alloying has been historically used for designating many different process routes, in spite of involving various kinds of materials and purposes. The aim of this work is to make a review of this technique, with special emphasis on the differences between those routes.

Nanocrystals by high energy ball milling

Nanostructured Materials, 1992
It has been shown that nanometer-size grains can be induced in even brittl e intermetallic compounds by high energy ball milling. The large grain boundary area provided by these nanocrystallites can help provide, along with the disordering energy, the driving free energy for the crystalline-to-amorphous transformation.

High-Energy Ball Milling of NiAl(Fe) System

Hyperfine Interactions, 2002
High-energy ball milling was used to promote the solubilization of iron into NiAl powder for an iron concentration range of 10–30 wt.%. The microstructural evolution induced by the intense mechanical deformations, under different milling conditions, was followed by X-ray diffraction and Mossbauer spectroscopy.

High energy ball milling of Co89B11 powders

Nanostructured Materials, 1999
Abstract Mechanical alloying was performed on elemental cobalt and boron powders with atomic ratio Co 89 B 11 . X-ray diffraction analysis (XRD) and differential scanning calorimetry were used to characterize the structure of the milled samples before and after the heating. The high-energy ball milling was found to influence the resulting phases. The
