Ball Milling Technique

An Al-5vol%Ti3SiC2 nanocomposite has been prepared by ball milling technique. Steel ball, agate ball and zirconia ball were selected during the ball milling process and then the microstructure evolution of the powder mixture was investigated. The homogenous fine mixed powder can be obtained with zirconia ball, whereas the conglomeration will be formed in the case of steel ball and agate ball. The bulk Al/Ti3SiC2 nanocomposite was fabricated by hot pressing technique. The effects of the particle size and agglomerate state of Ti3SiC2, as well as the microstructure of Al/Ti3SiC2 nanocomposite were studied by SEM and TEM. It was found that the nanosized Ti3SiC2 particle could be obtained during the ball milling process and distributed in aluminium homogenously.

The high energy mechanical alloying of a Ti–Ru–Fe powder mixture (atomic ratio 2 : 1: 1) has been performed by extensive ball-milling in a steel crucible. The structural evolution of the resulting materials has been studied by x-ray powder diffraction analysis. The identification of the various phases present in the materials, as well as the crystallite size and strain, has been performed by Rietveld refinement analysis. In the first stage of the material transformation, Ru or Fe atoms dissolved into Ti to yield to the formation of β–Ti. Upon further ball-milling, almost all the original constituents of the powder mixture have disappeared and a new simple cubic Ti2RuFe phase is formed, with a crystallite size as small as 8 nm. The electrochemical properties of these materials have been tested in a typical chlorate electrolyte by cold-pressing the powders into disk electrodes. At 20 h of ball-milling, where the phase concentration of Ti2RuFe reaches 96%, a reduction of the activation overpotential at 250 mA cm−2 of nearly 250 mV is observed when compared to that of a pure iron electrode.

High Temperature Synthesis

Nanostructured MoSi2 powder has been successfully synthesized by Ball milling of Mo and Si powder mixtures and subsequent self-propagating high-temperature synthesis (SHS) process. It was observed that in comparison with the normally mixed powder, it could be easily ignited and higher combustion temperature was achieved. Based on XRD and SEM, it was confirmed that nanostructure MoSi2 powder could be prepared through self propagating combustion method from the mechanical activated powder mixture.
