Abstract Grain refinement by severe plastic deformation (SPD) techniques, as a mechanism to control microstructure (recrystallization, grain size changes,…) and mechanical properties (yield strength, ultimate tensile strain, hardness variation…) of pure aluminium conductor wires, is topic great interest for both academic industrial research activities. This paper presents an innovative finite e...

An austenitic stainless steel with 6 wt% Si and multiple secondary phases was produced the aim to achieve enhanced plasticity during hot deformation. The microstructure of after fracture characterized via electron back-scattered diffraction, transmission Kikuchi diffraction scanning microscopy. From tail gage necking region, material evolved from low-angle grain boundaries (LAGBs) mixtures LAGB...

Recrystallization is one of the most important physical phenomena in condensed matter that has been utilized for materials processing for thousands of years in human history. It is generally believed that recrystallization is thermally activated and a minimum temperature must be achieved for the necessary atomic mechanisms to occur. Here, using atomistic simulations, we report a new mechanism o...

Isothermal interrupted hot compression tests of 5754 aluminum were conducted on a Gleeble-3500 thermo-mechanical simulator at temperatures of 350 °C and 450 °C, and strain rates of 0.1 s−1 and 1 s−1. To investigate the metadynamic recrystallization behavior, a range of inter-pass delay times (5–60 s) was employed. These tests simulated flat rolling to investigate how softening behaviors respond...

The comparative analysis of the effect of monotonous and non-monotonous severe plastic deformations (SPD) on the structure and properties of aluminum alloys has been carried out. Conventional hydrostatic extrusion (HE) with a constant deformation direction and equal-channel angular hydroextrusion (ECAH) with an abrupt change in the deformation direction were chosen for the cases of monotonous a...

This work is part of a wide-ranging study aiming to enhance the technology dissimilar friction-stir welding aluminum and titanium. In previous study, new approach was proposed that provided an exceptionally narrow intermetallic layer. However, essential disadvantage this technique significant material softening in part. Hence, present undertaken order obtain insight into microstructural process...
