The effect of structural relaxation on SANS and its anisotropy in a metallic glass
نویسنده
چکیده
2014 We report a large decrease in small-angle-neutron scattering (SANS) after relaxationannealing below Tg in glassy Pd80Si12Ge8 ribbons. We had previously reported here on the SANS in this alloy and its anisotropy which we attributed to defect orientations induced by the shearing action of the substrate during rapid solidification. We now attribute the decrease in the anisotropic SANS to the partial disappearance of these quenched-in defects during the relaxation anneal. Important contributions from crystallites and surface effects are excluded as they would tend to increase and not decrease the SANS. J. Physique Lett. 46 (1985) L-189 L-193 ler MARS 1985, Classification Physics Abstracts 61.40D

Glass is one of the oldest materials which have been used in human history. Till nowadays, glass has not lost its attraction. The macroscopically character of this object make it usable for many different applications. Whether its transparency or its opacity, this object is the most fascinating material. Indeed, the history of glass making goes back to the 3th Millennium BC in Near East and Lev...

A constant volume, atmospheric pressure Zr/Ba/Na fluoride glass has been simulated by molecular dynamics with the limitations of the Born-Mayer-Huggins potentials, used previously and resulting in high simulation pressures, having been overcome. The simulated structure of this glass as well as its activation energy for diffusion are in very good agreement with those experimentally observed. T...

Bulk metallic glass-forming Pd40Ni10Cu30P20 has been investigated in its equilibrium liquid by quasielastic neutron scattering. The quasielastic signal exhibits a structural relaxation as known from nonmetallic viscous liquids. Even well above the melting point, the structural relaxation is nonexponential and obeys a universal time-temperature superposition. From the mean relaxation times avera...

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...

Using wastes as starting raw materials is a common method to reduce the production costs and the environmental pollution problems arising from such wastes. In this study the production and crystallization behavior of an iron rich glass prepared by iron and steel making wastes has been investigated. The raw materials used, were the blast furnace slag, the blast furnace dust, converter slag and s...
