Transformations in oxides induced by high-energy ball-milling

open access: yesDalton Transactions, 2012
This paper, by no means exhaustive, focuses on high-energy ball-milling of oxides, on their mechanically induced changes and on the consequences of such changes on their physical and chemical properties. High-energy ball-milling offers a fortunate combination of technical simplicity and of complexity both of physical mechanisms which act during milling

Influence of high-energy ball milling of precursor on the morphology and electrochemical performance of Li4Ti5O12–ball-milling time

open access: yesSolid State Ionics, 2008
High-energy ball milling (HEBM) was applied for the synthesis of spinel Li4Ti5O12 and the influence of milling time was investigated systematically. With the increase of ball-milling time, the average particle size of the as-synthesized Li4Ti5O12 powder ...

The effect of high energy ball milling on the crystal structure of GDNi5 [PDF]

open access: possiblePhysica B: Condensed Matter, 2001
X-ray powder diffraction was used to determine the effect, of dry, in air performed high energy ball milling, on the intermetallic compound GdNi5. It was found that the crystal structure of GdNi5 is not stable, and at the early stage of milling (up to after 10 h of milling) it decomposes into the constituent metals gadolinium and nickel, whereby ...

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 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.

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.
