Superconductivity in Hierarchical 3D Nanostructured Pb–In Alloys

Accelerated sintering in phase-separating nanostructured alloys

Sintering of powders is a common means of producing bulk materials when melt casting is impossible or does not achieve a desired microstructure, and has long been pursued for nanocrystalline materials in particular. Acceleration of sintering is desirable to lower processing temperatures and times, and thus to limit undesirable microstructure evolution. Here we show that markedly enhanced sinter...

Microstructure of nanostructured amorphous Si-Au-alloys

Obstacles to applications of nanostructured thermoelectric alloys

A major theme in thermoelectric research is based on controlling the formation of nanostructures that occur naturally in bulk intermetallic alloys through various types of thermodynamic phase transformation processes (He et al., 2013). The question of how such nanostructures form and why they lead to a high thermoelectric figure of merit (zT) are scientifically interesting and worthy of attenti...

Serrated flow in nanostructured binary Mg-Al alloys

Article history: Received 2 August 2016 Received in revised form 14 September 2016 Accepted 15 September 2016 Available online xxxx Serrated flow, also known as the Portevin-Le Chatelier effect, has been extensively investigated in binary Mg-alloys such asMg-Ag,Mg-Y andMg-Li alloys. Interestingly, however, this effect has not been observed inMg-Al alloys. In this work, we report the appearance ...

Light Element Quantification in Irradiated Nanostructured Ferritic Alloys

As the local electrode atom probe, and almost all previous generations of instruments, use a time-of-flight mass spectrometer, atom probe tomography (APT) is able to detect, and in most cases quantify, all elements. However, an appropriate pulse repetition rate for the field evaporation pulse, and the associated timing window, must be selected to detect the entire range of elements present. Hen...
