AbstractThe quality of low-rigidity cylindrical parts after straightening by transverse rolling with smooth plates is considered. To simulate the straightening process, the ANSYS Workbench software package is used. The calculation results demonstrate that the quality of cylindrical parts after straightening depends mainly on the relative reduction....

AbstractA mechanical technique used to determine the surface residual stresses and four techniques used to harden samples are described. The diagrams of surface residual stresss in titanium and iron–chrome–nickel alloy samples before and after hardening are built based on experimental data. All titanium and iron–chrome–nickel alloy samples are foun...

The aim of this research was to examine the mechanical and fatigue properties of friction stir welded Sc-modified 5 mm thick AA2519-T62 extrusion. The joint was obtained using the following parameters: 800 rpm tool rotation speed, 100 mm/min tool traverse speed, 17 kN axial, and MX Triflute as a tool. The investigation has involved microstructure o...

AbstractThe phase composition of thin-sheet (0.3 mm thick) austenitic–martensitic VNS9-Sh TRIP steel is studied by X-ray diffraction, and the residual stresses in the steel are determined. This cold-rolled steel is a gradient material with a high content of strain-induced martensite in the near-surface layers. The austenite content in the surface l...

This study investigates the effects of axial ultrasonic vibration on the microstructure evolution, residual stresses distribution and fatigue fracture behaviour of a 7N01-T4 joint, and demonstrates that ultrasonic vibration can significantly promote the flow of plasticised metals, expand the stirred zone (SZ) width and refine the grain size. The lo...

The Rapid Additive Forging (RAF) process is a Direct Energy Deposition (DED) Additive Manufacturing (AM) process, based on the deposition of a Titanium alloy on a substrate plate. This process has been developed for the production of Titanium parts of aeronautic components. In this study, a Finite Element (FE) numerical simulation methodology has b...

AbstractThe present paper aims to develop geometrical approach for finite incompatible deformations arising in growing solids. The phenomena of incompatibility is modeled by specific affine connection on material manifold, referred to as material connection. It provides complete description of local incompatible deformations for simple materials. M...

Present work attempts to investigate machinability of Ti-5Al-2.5Sn for Electro-Discharge Machining (EDM). Extent of machinability is determined through material removal efficiency, tool wear rate, and surface integrity of the EDMed specimen of Ti-5Al-2.5Sn. Detailed analysis of surface morphology followed by study of surface topographical features ...
