Review on ultrafined/nanostructured magnesium alloys produced through severe plastic deformation: microstructures
A review on the microstructural evolution in magnesium alloys during severe plastic deformation waspresented. The challenges deserved to achieve ultrafine/ nanostructured magnesium were discussed.The characteristics of the processed materials are influenced by three main factors, including i)difficult processing at low temperatures, ii) high temperature processing and the occurrence ofdynamic r...

متن کاملStrengthening of Metals through Severe Plastic Deformation
The processing of bulk metals through the application of severe plastic deformation (SPD) provides an opportunity for achieving excellent grain refinement to the submicrometer or even the nanometer range. These SPD procedures produce materials exhibiting improved mechanical properties including very high strength. This report describes recent results demonstrating the strengthening of conventio...
متن کاملPlastic Flow and Grain Refinement Under Simple Shear-Based Severe Plastic Deformation Processing
In the present work, effects of loading scheme and strain reversal on structure evolution are studied by using high pressure torsion (HPT) and twist extrusion (TE) techniques. High purity aluminum (99.99%) was processed at room temperature up to a total average equivalent strain of ~4.8 by TE and HPT with two deformation modes: monotonic and reversal deformation with a step of 12 ̊ rotation. It ...
