Mixing of iron with various metals by high-energy ball milling of .

The alloying of Fe with T=V, Cr and Mn by high-energy ball milling of elemental powder mixtures has been studied from the scale of a powder particle down to the atomic scale using X-ray and neutron diffraction, Mössbauer spectrometry and magnetic measurements for Fe1−xTx alloys with x=0.50, 0.65 for T=V, x=0.50, 0.70.

Phase evolution induced by mechanical milling in Ln2O3:TiO2 .

Apr 29, 2005 . This paper presents a study of the phase evolution induced by mechanical milling in mixtures Ln2O3:TiO2 (Ln=Gd, Dy) with two different stoichiometries, 1:1 and 1:2. Starting from oxides, pyrochlores Ln2Ti2O7 and the hexagonal β-Ln2TiO5 forms were obtained at room temperature by milling the initial.

An investigation on the mechanism and reaction sequence of .

During the early stages of mechanical milling, mixing and particle refinement of powders occur. This is accompanied by the formation of fresh surfaces, high plastic strains and high densities of vacancies and dislocations. These crystal imperfections act as chemically active sites that can facilitate the ignition of MSR.

High energy ball milling of titania and titania–ceria powder mixtures .

TiO2 anatase powders transform to rutile after 3 h high energy ball milling. •. Rutile can be partially reconverted into anatase by a thermal treatment at 700 °C. •. High energy ball milled TiO2/CeO2 powder mixtures turn into rutile structure. •. TiO2/CeO2 recrystallization into anatase is reduced with increasing ceria content.

High energy ball milling process for nanomaterial synthesis

It is a ball milling process where a powder mixture placed in the ball mill is subjected to high-energy collision from the balls. This process was developed by Benjamin and his coworkers at the International Nickel Company in the late of 1960. It was found that this method, termed mechanical alloying, could successfully.
