Static and Dynamic Properties of Al-Mg Alloys Subjected to Hydrostatic Extrusion.

The aim of this study is to determine the influence of the amount of magnesium in Al-Mg alloys and strain rate on the grain refinement and mechanical properties of the material as determined in a dynamic tensile test. Hydrostatic extrusion was used to process the material. This method is not commonly used to impose severe plastic deformation of Al-Mg alloys.

Characteristics of the Structure, Mechanical, and Tribological Properties of a Mo-MoN Nanocomposite Coating Deposited on the Ti6Al4V Alloy by Magnetron Sputtering.

Mo-MoN nanocomposite coating was produced by reactive magnetron sputtering of a molybdenum target, in the atmosphere, of Ar and N gases. Coating was deposited on Ti6Al4V titanium alloy. Presented are the results of analysis of the XRD crystal structure, microscopic SEM, TEM and AFM analysis, measurements of hardness, Young's modulus, and adhesion.

Investigation into the Effect of RFSSW Parameters on Tensile Shear Fracture Load of 7075-T6 Alclad Aluminium Alloy Joints.

The aim of the investigations was to determine the effect of parameters of refill friction stir spot welding (RFSSW) on the fracture load and failure mechanisms of the resulting joint. RFSSW joints were made in 7075-T6 Alclad aluminium alloy sheets using different welding parameters. The load capacity of joints was determined under tensile/shear loadings.

Nanoscale Inhomogeneities Mapping in Ga-Modified Arsenic Selenide Glasses.

Nanoscale inhomogeneities mapping in Ga-modified AsSe glass was utilized exploring possibilities of nanoindentation technique using a Berkovitch-type diamond tip. Structural inhomogeneities were detected in Ga(AsSe) alloys with more than 3 at.% of Ga.
