We have performed constant temperature two-dimensional molecular dynamicssimulations of a binary Lennard-Jones material, representing an idealized metallic alloy or amaterial containing a specified fraction of an additive atomic species. Differences in the interatomicpotentials between the atomic species can lead to clustering of the alloy atoms. An exponentialdistribution of cl...

An overview of the synthesis and characterization of several Pt-Ru or Pt-MoNulcan carbon nanocomposites and one Pt-Rdgraphitic carbon nanofiber nanocomposite is provided. Each binary metal alloy nanocluster composition is accessed through the t h d decomposition of a single-source molecular precursor containing the desired metal stoichiometry. Microwave heating techniques are. used to form a Pt...

Titanium (Ti) has been used for long in dentistry and medicine for implant purpose. During the years, not only the commercially pure Ti but also some alloys such as binary and tertiary Ti alloys were used. The aim of this review is to describe and compare the current literature on binary Ti alloys, including Ti-Zr, Ti-In, Ti-Ag, Ti-Cu, Ti-Au, Ti-Pd, Ti-Nb, Ti-Mn, Ti-Mo, Ti-Cr, Ti-Co, Ti-Sn, Ti-...

Oxidation behavior of metastable mechanical alloys in the Al–Mg binary system has been examined in the context of high-energy density materials and combustion applications. Mechanical alloy powders with compositions ranging from Al0.95Mg0.05 to Al0.5Mg0.5, as well as the component metals, were heated at 20 K/min in oxygen. Differential thermal analysis and thermogravimetric analysis showed that...

Abstract The maximum undercooling that has been achieved for Ni-Cu alloy, by using molten glass purification and cyclic super-heating technology, is 270 K. With the help of high-speed photography, solidification front images alloy at various typical were obtained. Two grain refinements occurred in range 60 K< ΔT < 100 K > 170 K, became smoother, position appeared randomly. increase und...
