Cold in- and outdoor work can result in different adverse effects on human health. Health problems decrease performance and work productivity and increase the occurrence of accidents and injuries. Serious health problems can also result in absence from work due to sick leave or hospitalization. At its worst, work in cold conditions could be associated with deaths due to cold-related accidents o...

Cold rolled sheet metal often used in laser forming exhibits anisotropic properties, which are mostly caused by preferred orientations of grains developed during the severe plastic deformation. In present study, the textures of cold-rolled mild steel sheets are characterized and the influence of the plastic anisotropy on laser forming process is investigated. Deformation textures are measured i...

The theory of plasticity is the branch of mechanics that deals with the calculation of stresses and strains in a body, made of ductile material, permanently deformed by a set of applied forces. The theory is based on certain experimental observations on the macroscopic behavior of metals in uniform states of combined stresses. The observed results are then idealized into a mathematical formulat...

in this work, the strength of cold roll bond of the commercially pure titanium (cp ti) sheet and the effect of tio2 nanoparticles on bond strength was investigated. through the accumulative roll bonding process, which is considered among the important severe plastic deformation processes, the creation of suitable bonds plays a significance role in the ultimate strength of the bond. thus, resear...

Variation in microstructural features of 2024 aluminum alloy plastically deformed by equal channel angular pressing (ECAP) at room temperature, was investigated by X-Ray diffraction in this work. These include dislocation density dislocation characteristic and the cell size of crystalline domains. Dislocations contrast factor was calculated using elastic constants of the alloy such as C 11, C 2...

Dynamic testing of statically predeformed specimens of magnesium (AM50) shows that the failure strain increases with the level of prestrain. Interrupted and other dynamic tests show that the temperature rise prior to localization has only a minor influence on adiabatic shear band (ASB) formation. For all the tests, the dynamic deformation energy until ASB formation is found to be relatively con...

in this study, the effect of cold rolling process on the microstructure and texture evolution in 1wt. % si non-orientedelectrical steel was investigated. for this purpose, all samples were processed through single-stage hot rolling at1100 ° c and two-stage cold rolling (cross rolling and unidirectional rolling) with intermediate annealing at 650 °cfor 35 seconds. finally, all of them were fully...
