In situ observation of AZ61 Mg alloy with 1 and 5 wt% of Al2O3 in the scanning electron microscopy was performed to study influence of the weight fraction of Al2O3 particles on the deformation and fracture mechanism during tensile test. Structure of the experimental materials was also analysed; microstructures were heterogeneous, with randomly dist...

In the present work, we report the results of tribological studies on commercially pure copper (Cu 99.9%) in contact a with graphitic material. The samples under study were made with two types of micro-structures, i.e., a coarse-grained (CG) microstructure with an average grain size of 20-60 μm after annealing and a submicrocrystalline (SMC) micros...

Mechanical and wear properties of a series of copper and magnesium based composites with alumina dispersoid nanoparticles were studied. The initial states of the composites were further treated by severe plastic deformation (SPD) in order to achieve microstructures with very fine grains. All states, as-received and SPD treated ones were then charac...

The effect of equal channel angular extrusion (ECAE) on the mechanical behavior of AM60/Al2O3p magnesium metal-matrix nanocomposites was investigated. ECAE is a useful technique to produce bulk nanostructured materials through severe plastic deformation. The present magnesium metal-matrix composites (Mg MMCs) with 1 wt% nanosized Al2O3 particles fo...

Mechanical and wear properties of magnesium alloys based composite series with alumina dispersoid nanoparticles were studied. In order to achieve microstructures with very fine grains, the fabricated composites were further deformed and categorized as Severe Plastic Deformation (SPD). The as-received as well as the SPD treated states were character...

This paper studies the mechanical properties enhancement of AM60/Al 2O3p magnesium metal-matrix nanocomposites by equal channel angular extrusion (ECAE) that is a useful technique to produce bulk nano-structured materials by severe plastic deformation. The present magnesium metal matrix composites (Mg MMCs) with 1, 2 and 5 wt.% of nano-sized Al 2O3...

The work presents the results of tribological study of low-carbon steel (up to 0.2 wt % carbon) in three states: initial (hot-rolled), heat-treated (refined), and refined and further subjected to severe plastic deformation by equal-channel angular pressing. After the various treatment types, the steel samples are found to be in different structural...

This paper presents the results of tribological investigations conducted on steel 20 with the carbon content of up to 0.2%. The steel was studied in the three conditions: initial (hot-rolled), after heat-treatment (quenching+tempering) and after heat treatment with subsequent severe plastic deformation (SPD) performed by equal channel angular press...

This research chose nano-scaled Al2O3 granular materials as the reinforcement particle and used the modified disintegrated melt deposition (DMD) technique to integrate the particle Al2O3 p with AZ91D as the magnesium metal matrix composites (Mg MMCs). Subsequently, the melt soup was formed with rapid stirring, and the different heat treatment proce...

Traditionally, in order to increase the mechanical properties of mental or alloy, various kinds of thermal mechanical and thermal treatments was adapted to approve the strength of mental as well as to form the specific appearance. In this study, the equal channel angular pressing (ECAP) was utilized to achieve nano-structure of Steel 20 and Steel 4...

Results of investigation of the tribological contact characteristics of R18 tool steel in interface with AZ91D magnesium alloy hardened with SiC disperse powder filler and by severe plastic deformation (SPD)—specifically, equal-channel angular pressing (ECAP)—are presented. It is established that introduction of the SiC powder filler into the magn...
