Research project: Microstructure, Microtexture and Properties of Ultrafine-Grained Metals and Alloys Processes by Severe Plastic Deformation

Currently Active: 
Yes

This project is devoted to research of microstructure, microtexture and properties of ultrafine-grained metals and alloys processes by severe plastic deformation.  

Project Overview

Ultrafine-grained and even nanostructured materials can be manufactured using ultra-high straining by ECAP, HPT, machining and their combinations, such as machining of ECAP specimens, HPT of ECAP and HPT of machining chips.  This Project is devoted to investigations of the microstructures and microtextures of pure metals (copper, nickel and aluminium) subjected to different deformation processes to ultimately high imposed strains. A comparison of microstructure, dislocation density and microhardness developed during combinations of different strain paths will be performed.  All characteristics will be analyzed by x-ray, transmission and scanning electron microscopy, EBSD. The influence of different processing routes will be investigated in terms of the accumulated strain and microstructure refinement. The saturation in grain refinement will be studied in terms of recovery taking place during ultra-high strain deformation.
