The Effect of Strain Rate on the Deformation Processes of NC Gold with Small Grain Size

open access: yesCrystals, 2020
The strength of nanocrystalline (NC) metal has been found to be sensitive to strain rate. Here, by molecular dynamics simulation, we explore the strain rate effects on apparent Young’s modulus, flow stress and grain growth of NC gold with small size. The

Grain boundary saturation and grain growth

open access: yesScripta Materialia, 2004
Abstract In nanoscale alloys with strong segregation tendency, the grain size at metastable thermodynamic equilibrium is determined by the grain boundary energy, the enthalpy change of grain boundary segregation, and the solute excess of an equivalent grain boundary monolayer at saturation.

Influence of Hot Forging Parameters on a Low Carbon Continuous Cooling Bainitic Steel Microstructure

open access: yesMetals, 2020
Thermomechanical processing of low carbon bainitic steels is used to obtain a bainitic microstructure with good strength and toughness by continuous cooling after forging without the need of further heat treating, hence reducing manufacturing costs ...

Study on the Phase Selection and Debye Temperature of Hyper-Peritectic Al-Ni Alloy under High Pressure

open access: yesMetals, 2021
The phase selection of hyper-peritectic Al-47wt.%Ni alloy solidified under different pressures was investigated. The results show that Al3Ni2 and Al3Ni phases coexist at ambient pressure, while another new phase α-Al exists simultaneously when solidified
