In this work, we investigated the influence of composition on polycrystalline structure, elastic properties and fracture strength, ZrxSi1-x, NbxSi1-x, MoxSi1-x free-standing thin films that were deposited by magnetron sputtering subsequently annealed at 500 °C. Despite deviations from stoichiometric composition, crystalline structure all films, except for most Zr-rich corresponded to their resp...

Known as having a stress self-accommodation characteristic, the laser cladding shape memory alloy (SMA) coatings have been widely used in material failure repair. Nevertheless, their further development is greatly limited by low microhardness (250 HV0.2) and corrosion resistance. Benefiting from capability of refined grain adjusted microstructure, rare earth oxides play key role improving prope...

Abstract Grain refinement by severe plastic deformation (SPD) techniques, as a mechanism to control microstructure (recrystallization, grain size changes,…) and mechanical properties (yield strength, ultimate tensile strain, hardness variation…) of pure aluminium conductor wires, is topic great interest for both academic industrial research activities. This paper presents an innovative finite e...

Supplier Relationship Management (SRM) is an application that gives support to a company in the task of deciding which supplier to choose when a new supply has to be ordered. It is based on a measure of trust and provides several tools that visualize that measure and support its use on decision making.

Local mechanical responses near single grain boundaries (GBs) of 9.8 mol% Y2O3-stabilized ZrO2 bicrystals, SrTiO3 bicrystal, and Al2O3 polycrystal were investigated by nanoindentation at room temperature to reveal GB contributions the properties. Contrary concept Hall–Petch strengthening, hardness showed negligible variations among interiors, vicinities, just on GBs in samples. Importantly, may...

This study investigated attachment style differences in online relationships with regard to interaction characteristics and relationship satisfaction. The effect of relationship type was also taken into account in these investigations. The findings suggested that attachment style differences in interaction breadth and depth were present only in casual friendships. Preoccupied and dismissing ind...
