  • Ball-milling-induced amorphization in Ni x Zr y compounds

    A vibrating frame grinder has been instrumented for evaluating the amplitude and frequency of ball oscillation as a function of the amplitude of vibration of the frame and of the ball mass. Based on such measurements it is found that Ni x Zr y compounds become fully amorphized provided the specific milling intensity is greater than a temperature- and composition-dependent threshold value.

  • Optimization of ball milling parameters to produce

    Nov 11 2013 · Ball milling is a common method in the size reduction of material. The milling process produces nanopowders through the impact forces generated by action of centrifugal forces. Milling parameters such as milling time mass concentration and bead amount are important parameters that need to be considered in producing superfine powders.

  • Ball milling effects for induced carriers and reduced

    ball milling exists at which the crystallite size of the starting powder suddenly decreased. The grain size in the bulks sintered using ball-milled powders also decreased and thermoelectric properties were enhanced mainly by the induced carriers rather than by the reduction in thermal conductivity.

  • Ball Milling-Induced Combustion in Powder Mixtures

    Ball milling induces self propagating high temperature reactions in many highly exothermic powder mixtures. This phenomenon has been studied in a variety of reactions with titanium zirconium and hafnium. Several oxides (CuO Cu 2 O NiO Fe 3 O 4 and ZnO) were reduced with Ti Zr and Hf and the borides carbides silicides and sulfides of these metals were prepared from elemental mixtures.

    Jan 01 2002 · Ball milling induces self-sustaining reactions in many sufficiently exothermic powder mixtures. The process begins with an activation period during which size reduction mixing and defect formation take place. The MSR (mechanically induced self-propagating reaction) is ignited when the powder reaches a well defined critical state.
