چکیده
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 layers bimetallic are processed unevenly. An aluminum shell with initial grain size 22 microns up to 2 microns. steel core has a different transverse longitudinal sections. With 18 microns, after about 10 section 8 section.

Plastic deformation of 7075 Aluminum Alloy using Integrated Extrusion-Equal Channel Angular Pressing
Grain refinement improves the mechanical properties and formability of metals and alloys. So far, several different grain refinement methods have been proposed and studied. Severe plastic deformation is one of the most promising and efficient methods. Therefore, in the present study the possibility of imposing a two-step severe plastic deformation (Extrusion and Equal channel angular pressing) ...
متن کاملRe-strengthening in AA6063 Alloy During Equal Channel Angular Pressing
Equal channel angular pressing (ECAP) is carried out using two different configurations for the exit channel of the ECAP die, i.e., relieved and choked, with angles of 0.2 °. It is found that using a die with relieved exit channel, the sample was extruded for 6 passes with no surface cracks and an average cell size of 727 nm and a fraction of high angle grain boundaries of 54 % were achieved. M...
متن کاملMicrostructural evolution in a spray-cast aluminum alloy during equal-channel angular pressing
A spray-cast Al-7034 alloy was processed by equal-channel angular pressing (ECAP) to a total of 8 passes at 473 K and the pressed samples were examined using transmission electron microscopy, differential scanning calorimetry and electron back-scatter diffraction. It is shown that the grain size of the alloy is reduced to ~0.3 μm by ECAP and the high pressures associated with ECAP lead to a fra...

In this research, samples of AlMg0.7Si aluminum alloy are deformed up to three passes using equal channel angular pressing (ECAP). Formation of a sub-micron structure after three passes of ECAP is demonstrated. Microstructural stability of the samples is investigated at temperatures of 300-500 °C. At 300 °C, fine recrystallized structure forms after 10 min which remains stable when the ...
