Article history: Received 10 February 2016 Received in revised form 22 May 2016 Accepted 8 June 2016 Available online xxxx The relationships betweenmicrostructure, controlled by alloying elements prone to grain boundary segregation, and electrical resistivity in sputtered nanocrystalline Cu were investigated. We find a non-monotonic dependence of themean grain size on solute concentration for b...

This article reviews the most important achievements in the studies of the compositional (chemical) and magnetic ordering effects in the surface region of single-crystal binary alloys with different bulk structures. These alloys include the non-magnetic and magnetic concentrated substitutional binary systems which have a tendency to ordering (Au–Cu, Cu–Pt, Fe–Pt, Co–Fe, Fe–Ni, Al–Fe, Al–Ni, Pt–...

Ordering and segregation properties of Fe–Ni alloys and nanoalloys are investigated by means of Metropolis Monte Carlo (MMC) and molecular dynamics (MD) simulations. The model is based on an embedded atom potential which, according to thermodynamic integration, only stabilizes those phases that are observed experimentally. This stability is confirmed by MMC and the same phases are found stable ...

− The article surveys amorphous and nanocrystalline alloys for soft magnetic applications. Both materials have much in common starting from their way of production and ranging over to the key factors which determine their properties. Thus, the magneto-crystalline anisotropy is randomly fluctuating on a scale much smaller than the domain wall width and, as a consequence, is averaged out by excha...

The influence of composition and purity of titanium on the mechanical properties and the transformation temperatures of Ni-Ti alloy dental castings was investigated by tensile testing and differential scanning calorimetry (DSC). The compositions of the ingots were 49.0-49.2 at% of titanium content. Three grades of titanium of relatively high purity were used as starting materials. The result sh...

Two major areas of effort are encompassed: I. New Techniques for the Synthesis of Metals and Alloys The High Rate Physical Vapor Deposition (HRPVD) process is to be used for the following: 1. Preparation and characterization of Ni and Ni-20Cr alloy sheet 2. Synthesis of compounds Y-O., TiC, Si^N, by reactive evaporation and their characterization 3. Dispersion strengthened alloys, Ni-ZOCr-Y-O ,...

The composition dependence of field induced anisotropy KU of field annealed soft ferromagnetic Co1−xFex 89Zr7B4 and Co1−xFex 88Zr7B4Cu1 amorphous and amorphous/nanocrystalline “nanocomposite” melt spun ribbons is investigated. With the exception of the highest Co-containing alloys x 0.10 , the observations are discussed in terms of a superposition of directional pair ordering of Fe,Co atoms and...

Nanowire is a cylindrical nano-structure with nanometer dimensions. In this research, the studied nanowire was made from the magnetic triple Ni-Fe-Co alloy.&#10 We utilized ordered porous anodic aluminum oxide as a template for the nanowire deposition. The nanowire arrays were electrodeposited in the cylindrical pores of the oxide layer by AC potential in a simple sulfate bath. Then the relatio...
