One of the most important properties microalloyed steels is different microstructures which are obtained by changing thermomechanical processing parameters and steel composition. The control microstructure such as grain size, precipitates, dislocation structure inclusions highly effective to determine mechanical steels. strengthening can be done processesing due increase nucleation sides via ma...

In this study, thermo elastic stress analysis is performed on a cylinder made of laminated isotropic materials under thermomechanical loads. Laminated cylinders have many applications such as aerospace, automotive and nuclear plant in the industry. These cylinders generally performed under thermomechanical loads. Stress and displacement distribution of the laminated cylinders are determined usi...

Although electrosurgical instruments are widely used in surgery to cut tissue layers or to achieve hemostasis by coagulation (electrocautery), only little information is available concerning the inflammatory or immune response towards the debris generated. Given the elevated local temperatures required for successful electrocautery, the remaining debris is likely to contain a plethora of compou...

A new high-speed pin-on-bar type tribometer has been developed to study the variation of friction coefficient with respect local thermomechanical contact conditions between tool and workpiece when drilling C45 steel. The forces temperatures are measured over a range pin indent depths sliding velocities in open closed loop tribo-systems. tribometer’s ability recreate is demonstrated induced surf...

The thermomechanical properties of shape memory effect and superelasticity due to the martensitic transformation and the R-phase transformation of TiNi shape memory alloy were investigated experimentally. The transformation line, recovery stress and fatigue property due to both transformations were discussed for cyclic deformation. The thermomechanical properties due to the R-phase transformati...

in the present study, an ultrafine grained (ufg) 304l stainless steel with the average grain size of 300 nm was produced by a combination of cold rolling and annealing. weldability of the ufg sample was studied by nd: yag laser welding under different welding conditions. taguchi experimental design was used to optimize the effect of frequency, welding time, laser current and laser pulse duratio...

Impurity elements of Cu, Ni, Sn and Cr have been added to a model low-carbon strip steel mimic the levels that could arise due increased scrap recycling during production. The microstructure tensile properties base composition impurity compositions after thermomechanical processing, consisting hot rolling simulated coil cooling, investigated. addition impurities results in lower bainite fractio...
