Strain hardening behaviors and strain rate sensitivity of gradient-grained Fe under compression over a wide range of strain rates [PDF]
Mechanics of Materials, 2016 In the present work, gradient-grained Fe was synthesized by means of surface mechanical grinding treatment, and then the compression behaviors of the coarse-grained Fe and the gradient-grained Fe were investigated under both quasi-static and dynamic loading conditions over a wide range of strain rates (from 5 x 10(-4) to 10(4) s(-1)).

Effect of strain rate on bake hardening response of BH220 steel
EPJ Web of Conferences, 2015 This study aims at understanding the bake hardening ability of ultra low carbon BH220 steel at different strain rates. The as-received material has been pre-strained to four different levels and then deformed in tension under (a) as pre-strained state ...

Microscopic Investigation of the Strain Rate Hardening for Polycrystalline Metals [PDF]
Transactions of Materials Processing, 2008 Polycrystalline materials such as steels(BCC) and aluminum alloys(FCC) show the strain hardening and the strain rate hardening during the plastic deformation. The strain hardening is induced by deformation resistance of dislocation glide on some crystallographic systems and increase of the dislocation density on grain boundaries or inner grain. However,

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.

Influence of Temperature on Mechanical Properties, Fracture Morphology and Strain Hardening Behavior of a 304 Stainless Steel [PDF]
Materials Research, 2017 The strain hardening behavior of an AISI 304 stainless steel at different temperatures was investigated in this work. Specimens were tensile tested up to rupture at temperatures of 25, 50, 75, 100, 125 and 150 ºC by using a universal testing machine with

Tensile Strain Hardening Behavior and Fractography of Superalloy GH39
Journal of Aeronautical Materials, 2016 The strain hardening behaviour and fractography of superalloy GH39 was investigated by tensile test at different strain rates. Results indicate that strain hardening behaviours are different during the deformation process.
