Research project: SPD processing of various metallic alloys

Currently Active: 
Yes

This project is investigating the potential for applying various severe plastic deformation (SPD) techniques to develop high strength and good ductility in some commercial metallic alloys, thereby enlarging the possible application for various materials including Mg alloys, Al alloys, Ti alloys and steel.  

Project Overview

Severe plastic deformation (SPD) provides the opportunity for developing ultrafine-grained and nanostructured materials. Among the numerous SPD techniques, equal-channel angular pressing (ECAP) and high-pressure torsion (HPT) are especially attractive because they produce the smallest grain sizes and the highest strengths. Therefore, it is possible to achieve exceptional strength and superplastic forming capabilities, as well as good wear resistance and corrosion resistant properties.

Selected materials will be processed by either equal-channel angular pressing (ECAP) or high-pressure torsion (HPT) or combinations of both. The relationship between microstructure and mechanical properties will be studied using various materials characterisation techniques and mechanical testing methods.
