Abstract The evolution of grain size and component mechanical behaviour are fundamental aspects to analyse control when manufacturing processes considered. In this context, severe plastic deformation (SPD) processes, in which a high shear strain is imposed on the material, recognized as main techniques achieve microstructural changes material strengthening by recrystallization, attracting both ...

A demand for cheap and simple methods of processing nanocrystalline materials attracted attention to metal forming techniques allowing introduction large strains into metallic materials. Thanks that a new scientific field, “Materials by severe plastic deformation”, had been born became an important segment material science. High pressure torsion (HPT) is the most effective SPD method in respect...

Abstract In this overview, the applicability of X-ray diffraction line profile analysis (XLPA) for characterization microstructure in nanostructured materials is overviewed. The dislocation densities obtained by whole pattern fitting and from breadth peaks are compared. Both theoretical considerations experimental evidences prove that evaluation peak solely not suitable determination density. a...

Abstract In the work, from standpoint of a systematic approach, methodology for technological design repair and restoration worn parts using methods to improve quality working layer is proposed. For stages product life cycle, solving problem extending service after parts, general scheme structure information support were developed that ensure layer. A variant process cylinder liners modified gr...

Ultrasound is widely used in the treatment of materials. Its applications melt processing, surface hardening or finishing, metal forming, welding, etc., are well known and have been reviewed numerous review articles books. Among ultrasound-assisted processes, direct action ultrasonic waves on structure properties bulk materials special interest. Ultrasonic induce oscillating shear stresses whic...

Tubular channel angular pressing (TCAP) is a recently invented novel severe plastic deformation technique for producing UFG tubes. Plastic deformation analysis using the finite element method (FEM) was carried out to investigate the effects of trapezoidal channel geometry on strain inhomogeneity index (SII), strain level and required load compared to previously used channel geometries. The resu...

In this study, HA is superplastically embedded into Titanium substrate and the sample is subsequently deformed superplastically until 70% deformation degree. The former process is termed as superplastic embedment (SPE) while the later as superplastic deformation (SPD). After the SPE, HA is successfully embedded into the substrate, forming a layer with a thickness of about 249 nm. After the SPD ...

The current study conducted a finite element (FE) and experimental investigation on tubular channel angular pressing as a noble severe plastic deformation technique for producing ultrafine grained and nanostructure tubular components. To examine the effects of the TCAP process on the strain distribution and deformation behavior, FE simulations were employed. The FE results demonstrated that equ...
