Ultrafine-Grained Ti-13Nb-13Zr Alloy Produced by Severe Plastic Deformation [PDF]

Materials Research, 2017
Biomedical devices currently in use (prostheses, implants) have satisfactory performance in many cases. However, sometimes the body reacts to the device insertion and may lead to its rapid replacement. Some of these disadvantages can be solved by the use

Vacancy clusters in ultrafine grained Al by severe plastic deformation [PDF]

, 2007
Bulk nanostructured metals are often formed via severe plastic deformation (SPD). The dislocations generated during SPD evolve into boundaries to decompose the grains.

Dynamic and post-dynamic recrystallization under hot, cold and severe plastic deformation conditions

, 2014
The evolution of the new microstructures produced by two types of dynamic recrystallization is reviewed, including those brought about by severe plastic deformation (SPD). The microstructural changes taking place under these conditions and the associated

Nanograin formation in dimple ridges due to local severe-plastic-deformation during ductile fracture

, 2021
Nanograin materials have superior properties in mechanics, physics and chemistry. Here, we found a new phenomenon that nanograin formation spontaneously occurs in the process of ductile fracture for a titanium alloy, and the dominating mechanism is local
