Microstructure et usinabilité d'alliages de titane béta-métastable

Titanium has become in recent years an interesting material in many applications that require a combination of high mechanical properties and low density. It has the peculiarity of undergoing an allotropic transformation at 882°C. Below this temperature, ...

Micromechanics of oxide inclusions in ferrous alloys

Alejandra Inés Slagter

Oxide inclusions are inevitably present in steel as a direct consequence of the steelmaking process; as a result, a cubic centimetre of modern steel will generally contain about a million of these hard and brittle micrometre-sized ceramic particles. Inclus ...

Geometric tolerances of welded connections with inelastic panel zones

Ce Wen, Dimitrios Lignos, Andronikos Skiadopoulos

Prequalified beam-to-column connections in steel moment resisting frames usually concentrate inelastic deformations in the steel beam ends. As such, nonlinear geo-metric instabilities (i.e., local buckling) may occur in these regions at modest lateral drif ...

Improved Waste Heat Management and Energy Integration in an Aluminum Annealing Continuous Furnace Using a Machine Learning Approach

Mohammad Andayesh, François Maréchal, Daniel Alexander Florez Orrego

Annealing furnaces are critical for achieving the desired material properties in the production of high-quality aluminum products. In addition, energy efficiency has become more and more important in industrial processes due to increasing decarbonization r ...

The influence of lattice misfit on screw and edge dislocation-controlled solid solution strengthening in Mo-Ti alloys

William Curtin, Carolina Baruffi, You Rao

Mo-Ti alloys form solid solutions over a wide range of compositions, with lattice misfit parameters increasing significantly with titanium content. This indicates a strong increase in the critical stress for edge dislocation motion. Here, we probe the tran ...

Quantitative study of the thickness-dependent stress in indium tin oxide thin films

Blaise François Cuénod, Rémy David Désiré Juttin

A quantitative analysis of stress in indium tin oxide (ITO) films with varying thicknesses was conducted using high-precision stylus profilometry. The experimental results revealed a transition of the stress type from tensile to compressive as the ITO film ...

Annealing hardening and softening of an ultrafine grained Cu-4.5vol.% Al2O3 nanocomposite

Roland Logé, Jun Wang

Samples from an ultrafine-grained Cu-4.5vol.%Al2O3 nanocomposite rod fabricated by powder compact extrusion were annealed at 400 and 700 degrees C for 15 min respectively, and their microstructure and mechanical properties were investigated. It shows that ...
