An Evaluation of the Mechanical Properties, Microstructures, and Strengthening Mechanisms of Pure Mg Processed by High‐Pressure Torsion at Different Temperatures

Pure Mg samples are processed by high-pressure torsion (HPT) for up to ten turns at temperatures of 293 and 423 K. The microstructures these significantly refined bimodal structures obtained after 10 HPT processing both Tensile experiments conducted room temperature reveal the mechanical properties pure subjected different temperatures. yield strength increases with increasing numbers K whereas shows almost no variation exhibits a higher strain hardening ability larger uniform elongation than Calculations show that grain size, structure, dislocation density main factors affecting material work behavior.
