Recovery of strain-hardening rate in Ni-Si alloys. [PDF]
Sci Rep, 2015 AbstractIn this study, the recovery of strain-hardening rate (RSHR) was discovered for the first time in polycrystalline materials (Ni-Si alloys) that have only dislocation activities during tensile test. Detailed microstructure characterizations show that the activation of dislocations in the secondary slip systems during tensile deformation is the ...

Influence of Strain Hardening Rate of Material on Temperature and Strain Distributions during Wire Drawing. [PDF]
Materials (Basel), 2023 Temperature rise of a specimen is a significant issue in drawing industries for wire, rod, and bar products, because an excessive increase in temperature during the drawing process can deteriorate the product quality and die life. The influence of the strain hardening exponent (n) of a wire on the temperature and strain distributions during wire ...

Nonmonotonic Strain Rate Dependence on the Strain Hardening of Polymer Nanocomposites
ACS Macro Letters, 2020 This Letter investigates the external deformation on modifying the polymer-nanoparticle (NP) and NP-NP interactions as well as their influences on the macroscopic properties of polymer nanocomposites (PNCs). Specifically, the applied uniaxial extension brings together the NPs along the transverse stretching direction and catalyzes the percolation ...
