Effect of HPT and CGP Processes on the Copper Me-chanical Properties
One of the most common methods for production of ultra fine grained materials is severe plastic deformation (SPD). In this study, constrained groove pressing (CGP) and high pressure torsion (HPT) processes as effective methods of severe plastic deformation for the strain imposed on the pure copper were used. This paper presents the results of an experimental research, to review the influence of...
متن کاملComparison of Hardness Values of Various specimens with different geometries and material properties after ECAP
Nowadays, equal channel angular pressing, known as the ECAP process, is one of the most popular methods for manufacturing ultra-fine grained (UFG) materials. In this paper, Ecap process has been carried out on pure copper and 6012 aluminum alloy up to six passes by route . Principal attention was paid to the influence of parameters such as diameter, material, and the height of billet on mechani...

متن کاملStrained thin copper films as model catalysts in the materials gap
Thin copper films on silicon constitute model systems to investigate the influence of lattice strain on activity in heterogeneous catalysis. Thin copper films on silicon were investigated by ultraviolet photoelectron spectroscopy (UPS) to reveal the effect of strain in the copper films on the electronic structure of the surface. For cleaned and adsorbate-free surfaces, no effect of strain on th...
متن کاملEffect of Cu Content on TiN-Cu Nanocomposite Film Properties: Structural and Hardness Studies
Titanium nitride-Copper (TiN-Cu) nanocomposite films were deposited onto stainless steel substrate using hollow cathode discharge ion plating technique. The influence of Cu content in the range of 2-7 at.% on the microstructure, morphology and mechanical properties of deposited films were investigated. Structural properties of the films were studied by X-ray diffraction pattern. Topography of t...
