Formation of glassy Ti50Cu20Ni24Si4B2 alloy by high-energy ball milling
The elemental powder mixtures with a nominal composition of Ti50Cu20Ni24Si4B2 can be amorphized under high-energy ball milling. A well-defined glass transition before crystallization appears in the obtained amorphous phase during heating in a differential scanning calorimeter. Awide supercooled liquid region DTx is available to be about 57 K. Crystallization of the ballmilled amorphous phase wa...
متن کاملFacile synthesis and regeneration of Mg(BH4)2 by high energy reactive ball milling of MgB2.
We report direct hydrogenation of MgB(2) in a planetary ball mill. Magnesium borohydride, Mg(BH(4))(2), and various polyhedral borane anion salts have been synthesized at pressures between 50 and 350 bar H(2) without the need for subsequent isothermal hydrogenation at elevated temperature and pressure. The obtained products release ∼4 wt% H(2) below 390 °C, and a major portion of Mg(BH(4))(2) t...
متن کاملMechanical Synthesis of Iron and Nickel Solid Solution by High Energy Ball Milling for Packaging
Mechanical alloying (MA) is a solid-state powder processing technique involving repeated cold welding and fracturing of powder particles in a high-energy ball mill. It has been used to obtain nanocrystalline binary system FeNi. Fe and Ni elemental powders have been ball milled in a planetary mill (Pulverisette5, Fritsch) for various times up to several hours. The morphology of the powders was e...
متن کاملSynthesis of Wurtzite Nano-crystalline ZnO-CoO Pigment by High Energy Milling
Zn0.9Co0.1O ceramic pigments were synthesized using simple high energy milling method. Zinc and cobalt oxides were used as starting materials. Products were investigated using simultaneous thermal analysis and fourier transformation infrared. Pigments were characterized using X-ray diffraction, diffuse reflectance and Scanning Electron Microscopy. The results showed the effect of calcination te...
