Structural relaxation of Ti40Zr25Ni8Cu9Be18 bulk metallic glass

The enthalpy relaxation behavior of Ti40Zr25Ni8Cu9Be18 bulk metallic glass follows the general characteristics of that for amorphous materials although its unique quenched-in nuclei/amorphous matrix structure: the annealing time dependence of recovery enthalpy follows a stretched exponential function with the mean relaxation time obeying an Arrhenius law, which may be due to the longer incubati...

Investigation of Magnetic Abrasive Finishing on Inner Surface of AL 6061 Tube

In magnetic abrasive finishing (MAF), abrasive grains as a tool move on surface and can remove chip from surface of work piece. In this study AL 6061 tube was considered as the work piece and the effect of finishing parameters such as gap distance between tube and poles, rotational speed of tube, abrasive ration and finishing time on surface roughness was investigated. The mixture of ferromagne...

Nanoscale structure and structural relaxation in Zr50Cu45Al5 bulk metallic glass.

Hybrid reverse Monte Carlo simulations of the structure of Zr50Cu45Al5 bulk metallic glass incorporating medium-range structure from fluctuation electron microscopy data and short-range structure from an embedded atom potential produce structures with significant fractions of icosahedral- and crystal-like atomic clusters. Similar clusters group together into nanometer-scale regions, and relaxat...
