Abstract. Extensive research on severe plastic deformation (SPD) of metallic materials has been performed so far in order to improve mechanical properties, both at low and high temperatures. As a result the extensive grain refinement obtained, increased superplastic behaviour attained higher strains rates lower temperatures than usual. This is due finer sizes average misorientations which enhan...

Abstract. The electro-superplastic effect (ESP effect) can enhance the superplastic deformation ability of alloy, and also make alloy with poor plasticity have properties. Diverse grain sizes LZ91 Mg-Li were successfully prepared through equal channel angular pressing (ECAP) process. In order to explore behavior under electric current, an field assisted uniaxial tensile test platform was design...

Abstract. This research presents the microstructural evolution and mechanical properties of a hypoeutectic AlSi11Cu alloy obtained through laser powder bed fusion (L-PBF) subsequent severe plastic deformation. The as-built demonstrated structure formed by an Al matrix surrounded Si-enriched cellular network. Tensile tests indicated yield strength 350 MPa elongation to fracture lower than 5% for...
