Cast AZ31B-H24 magnesium alloy, comprising Mg with 3.27 wt% Al and 0.96 wt% Zn, was cold rolled and subsequently annealed. Global texture evolutions in the specimens were observed by X-ray diffractometry after the thermomechanical processing. Image-based microstructure and texture for the deformed, recrystallized, and grown grains were observed by electron backscattered diffractometry. Recrysta...

It is quite plausible that the mass of the dark matter particle increases significantly after its freeze-out, due to a scalar field rolling to large values. We describe a realization of this scenario in the context of thermal inflation which naturally gives a cold dark matter particle with the correct cosmological abundance and a mass around 10 GeV, evading the conventional upper bound of 10 Ge...

The spark plasma sintering (SPS), subsequent cold rolling, and annealing were used to produce Ti-Cu alloys improve mechanical properties antibacterial rate against Staphylococcus aureus significantly. tensile strength, elongation reached 683.4 MPa, 21.6% 95%, respectively. insights for the improvement have been attributed high-density in-situ Ti2Cu precipitates in refined grain structures after...

research scientist, Quaker Chemical Corp., Uithoorn, The Netherlands [email protected] Cold rolling involves intensive frictional contact between two highly loaded metallic surfaces in sliding contact. Together with the deformation-related parameters, such as hardness and reduction, the frictional conditions in the roll bite determine the roll forces and torques required for rolling (Figu...

The effect of thermos-mechanical processing and thermal treatments on the microstructure a single phase fcc-based Al5Co15Cr30Fe25Ni25 high entropy alloy is evaluated in this study. As-cast ingots were thermo-mechanically processed following different routes involving forging, cold rolling, warm rolling or hot rolling. In addition, microstructural evolution highly deformed rolled sheets with ann...

Deformation behaviors during cold rolling and static recrystallization upon subsequent annealing of an extruded WE43 alloys with different initial textures were investigated in this study. Three types differently textured labeled as samples I, II III. The results showed that multiple twinning modes basal slip dominated the deformation rolling. Cold-rolled sample I activated larger number double...

We report on a comparative Atomic Force Microscope (AFM) multi-scale roughness analysis of cold rolled Al alloy and steel roll, in order to characterize the roughness transfer from the steel roll to the workpiece in cold strip rolling processes. More than three orders of length-scale magnitudes were investigated from 100 microns to 50 nanometers on both types of surfaces. The analysis reveals t...

Cold rolling process is a complicated process which can be optimized by changing in variables and settings. This paper presents a set-up optimization system developed to calculate reductions and inter-stand tensions for each stand of a five stand tandem cold mill. The main objective in this optimization is minimization of power consumption. First, by using the analytical method, the equations ...
