Glass Formation In A (Ti,Zr,Hf)-(Cu,Ni,Ag)-Al High-Order Alloy System By Mechanical Alloying, L C. Zhang, Z Q. Shen, Jian Xu Jan 2003

Glass Formation In A (Ti,Zr,Hf)-(Cu,Ni,Ag)-Al High-Order Alloy System By Mechanical Alloying, L C. Zhang, Z Q. Shen, Jian Xu

Faculty of Engineering and Information Sciences - Papers: Part A

In this work, glass formation under high-energy ball milling was investigated for a (Ti0.33Zr0.33Hf0.33)50(Ni0.33Cu0.33Ag0.33)40Al10 high-order alloy system with equiatomic substitution for early and late transition-metal contents. For comparison, an amorphous alloy ribbon with the same composition was prepared using the melt-spinning method as well. Structural features of the samples were characterized using x-ray diffraction, transmission electron microscopy, and differential scanning calorimetry. Mechanical alloying resulted in a glassy alloy similar to that obtained by melt spinning. However, the glass formation ...

The 21-cm line emission from a 7 × 6 deg2 region east of and adjoining the Small Magellanic Cloud (SMC) has been observed with the Australia Telescope Compact Array and the Parkes telescopes. This region represents the westernmost part of the Magellanic Bridge, a gas-rich tail extending ∼14° to the Large Magellanic Cloud. A rich and complex neutral hydrogen (H i) structure containing shells, bubbles and filaments is revealed. On the larger scale, the H i of the Bridge is organized into two velocity components. This bimodality, which appears to originate in the SMC, converges to a single velocity component ...
