In this study, five MgZnCa alloys with low alloy content and high biocorrosion resistance were investigated during thermomechanical processing. As documented by microhardness tensile tests, pressure torsion (HPT)-processing subsequent heat treatments led to strength increases of up 250%; as much about 1/3 increase was due the treatment. Microstructural analyses electron microscopy revealed a significant density precipitates, but estimates Orowan exhibited values smaller than observed....
The harmonic structure is a recently introduced concept paving the way for engineering metallic materials to achieve excellent mechanical performance. They consist of soft coarse-grained regions (Core) that are three-dimensionally surrounded by connected network hard ultra-fine grained (Shell). interaction in these Core–Shell produces synergistic effect, during plastic deformation, leading superior properties extremely important practical applications. current review paper aimed at providing...
Creating bimodal grain size distribution in crystalline materials is an effective strategy to improve structural efficiency. Present investigation demonstrates that further control over topology through the formation of ‘harmonic’ structure simultaneously increases average values strength and ductility, reduces variation corresponding properties, thwarts localization plastic flow.
Materials having bimodal grain structures are known for the good balance of strength and ductility. However, methods their fabrication often lack control such structure characteristics. In this work, principles "harmonic" allowing to both topology scale heterogeneity have been concisely formulated. The feasibility form "harmonic structure" in pure copper has demonstrated, advantages tensile performance material with a is analyzed.
Abstract In the light of recent developments in design structural materials, micro-architected heterogenous-structure metals are considered among most structurally efficient. this work, a new technique for Local High Pressure Torsion (L-HPT) enabling creation heterogeneous structures through localised deformation processing sheet by impeding rotating punch is proposed. Using AA5083 aluminium alloy as an example, we show experimentally that rotation sets adjacent material layers motion. This...
High purity Al (99.99%) was subjected to severe plastic deformation through twist extrusion at room temperature. Microstructures were examined for 1 pass and 4 passes on the cross section perpendicular longitudinal axis of billets using optical microscopy electron back scatter diffraction analysis. It shown that a vortex-like material flow observed this became more intense with increasing number pressing. After one pass, subgrain structures low angle grain boundaries developed throughout but...
