Hot compression tests were conducted using a Gleeble 3500 thermomechanical simulator at temperatures ranging from 1,000 to 1,200°C with the strain rate 0.1 10 s −1 . Electron backscatter diffraction (EBSD) technique was employed by investigating microstructure evolution during hot deformation. Microstructure observations reveal that deformation and rates have significant effect on DRX process. ...

The hot deformation behavior and microstructural evolution of an Al-Zn-Mg-Cu (7150) alloy was studied during hot compression at various temperatures (300 to 450 °C) and strain rates (0.001 to 10 s-1). A decline ratio map of flow stresses was proposed and divided into five deformation domains, in which the flow stress behavior was correlated with different microstructures and dynamic softening m...

experiments were carried out in which the dependence of the fractional softening on temperature, time and strain rate was determined in a 304h stainless steel. three prestrain ranges were identified pertaining to three different post-deformation softening behaviors: 1) prestraining to below the drx critical strain: strongly strain dependent softening by srx alone with softening kinetics control...

A partially recrystallized sample of the Ni-based superalloy AD730 was taken from an intermediate stage ingot to billet conversion process and isothermally forged in a single stroke compression test at sub-solvus temperature (1080 °C). The as-received material had heterogeneous microstructure, containing mixture coarse much finer grains as well unrecrystallized ones, also γ′ precipitation. recr...

Disordered rocksalt (DRX) Li3V2O5 is a promising anode candidate for rechargeable lithium-ion batteries because of its low voltage, high rate capability, and good cycling stability. Herein, we present comprehensive study the intercalation chemistry DRX-Li3V2O5 using density functional theory (DFT) calculations combined with machine learning cluster expansions interatomic potentials. The predict...

The role of microstructure on hot deformation behavior of sintered Cu-28Zn prealloyed powder compacts was investigated by a series of isothermal hot compression tests in the temperature range of 550- 850°C at strain rates of 0.001, 0.01, 0.1 and 0.5 s-1, by taking into consideration the Hyperbolic Sine functional behavior to analyze the deformation behavior of the alloy. The results indicate th...

The development of Li-excess disordered-rocksalt (DRX) cathodes for Li-ion batteries and interpretation through the framework percolation theory Li diffusion have steered researchers to consider “Li-excess” (x > 1.1 in LixTM2−xO2; TM = transition metal) as being critical achieving high performance. It is shown that this not necessary Mn-rich DRX-cathodes demonstrated by Li1.05Mn0.90Nb0.05O2 Li1...

To better understand the tensile deformation and fracture behavior of 35CrMo steel during hot processing, uniaxial tensile tests at elevated temperatures and strain rates were performed. Effects of deformation condition on the flow behavior, strain rate sensitivity, microstructure transformation, and fracture characteristic were characterized and discussed. The results indicated that the flow s...
