Possibilities of application methods drece in forming of non-ferrous metals [PDF]
Device “DRECE - Dual Rolls Equal Channel Extrusion” is used for production of metallic materials with very fine grain size (UFG). During the actual forming process the principle of severe plastic deformation is used.

From Damage to Functionality: Remanufacturing of Thrust Roller Bearings by Tailored Forming
Herein, the wear and fatigue behavior of repaired bearing raceways with a new powder alloy is investigated using a FE8 test‐rig and an oscillating tribometer. The tests are compared with industrial manufactured bearings to evaluate the repair quality. The repair can extend the service life of the repaired bearing to that of a new bearing and improves ...

Microstructure evolution during severe plastic deformation [PDF]
Radiotracer diffusion studies of severely deformed, ultra-fine grained materials have revealed the presence of ultra-fast transport paths, which include "non-equilibrium" grain boundaries and free volume. Under some experimental conditions, percolating porosity is produced even in pure copper [Ribbe et al., Phys. Rev. Lett. 2009]. Micro-cracks may form

Severe plastic deformation of metals
This paper provides an introduction in the field of severe plastic deformation (SPD). First of all the main methods to produce SPD materials are discussed. In the following section, the mechanisms leading to the formation of fine grains are reviewed and the influence of changes in strain path is highlighted.

A Novel Simulation Approach for Damage Evolution during Tailored Forming
Traditional damage models are struggling to accurately and efficiently simulate large‐scale three‐dimensional models with a great number of degrees of freedoms. A new gradient‐enhanced damage model based on the extended Hamilton principle can significantly reduce the computation time while ensuring mesh‐independence which is suitable to use in tailored

Effects of Surface Severe Plastic Deformation on the Mechanical Behavior of 304 Stainless Steel
In this study, two innovative surface severe plastic deformation (SSPD) methods, namely abrasive waterjet peening (AWJP) and ultrasonic nanocrystal surface modification (UNSM), were applied to a 304 stainless steel to improve the mechanical behavior. The

Закономерности влияния кручения под высоким давлением на структуру и прочностные свойства высокоазотистой аустенитной стали Х18АГ23Ф3 [PDF]
The microstructure and microhardness of high-nitrogen austenitic steel Fe-18Cr-23Mn-2,7V-0,2C-0,7N (in wt. %) after upset and high-pressure torsion (HPT) (6GPa) for 1/4, 1/2, and 1 revolutions at room temperature have been investigated.
