During experimental studies of the equal-channel angular pressing-drawing effect on microstructure evolution and mechanical properties change, principal possibility effectiveness using proposed continuous method for forming an ultrafine-grained structure increasing strength steel-aluminum wire was proved. The deformation carried out at ambient temperature in three passes. It is shown that both ...
Purpose. To investigate the diagnostic accuracy of the overlapping infinity loops, wire cube, and clock drawing tests (CDT) in the detection of mild cognitive impairment (MCI) and dementia. Method. The participants were 60 normal controls (NC), 35 patients with MCI, and 47 patients with mild dementia. Results. The results illustrate that infinity loops, cube, or CDT were not able to discriminat...
The paper’s authors researched the defects correction for RSt 34-2 (1.0034) steel wire, obtained as result of its overheating at 1140...1160 °C. Instead re-heat treatment method, proposed five cold drawing, annealing and combination schedules, which ensure increase in strength to DIN EN ISO 6892-1-2020 requirements. experiments were performed on 4 mm diameter wire with increased grain size (up ...
The fracture performance of axisymmetric notched samples taken from pearlitic steels with different levels cold-drawing is studied. To this end, a real manufacture chain was stopped in the course process (on-site factory), and all intermediate stages were extracted initial hot-rolled bar (not cold-drawn at all) to final commercial product (prestressing steel wire). Thus, drawing intensity or st...
We have developed a low-cost and effective method to align single-walled carbon nanotubes (SWNTs) using a series of diamond wire drawing dies. The obtained SWNTs are highly dense and perfectly aligned. X-ray diffraction (XRD) indicates that the highly dense and perfectly aligned SWNTs (HDPA-SWNTs) form a two-dimensional triangular lattice with a lattice constant of 19.62 A. We observe a sharp (...
Mill scale (MS) is a iron-rich waste generated in the wire drawing process with high iron content and still mainly disposed landfills. The scientific community has been studied its use other applications such as pigments, concretes, among others. This work aims to study new added-value application for MS—the development of coloured ceramic pastes. For this purpose, influence added amount (0, 1,...
