Effect of loading modes on torsional behavior of an extruded Mg alloy bar
Journal of Materials Research and Technology, 2022 The torsional deformation with shear stress is crucial for improving mechanical performance of wrought Mg alloys. Consequently, the difference of mechanical behavior between fixed-end and free-end torsion was investigated.

Plastic flow behavior of twinning induced plasticity steel from low to warm temperatures
Journal of Materials Research and Technology, 2020 This work investigates the tensile behavior of twinning induced plasticity (TWIP) steel under room to warm temperatures. Stress-strain flow curves have been obtained from steady-state uniaxial tensile tests performed at different temperatures, that is ...
