RISConstitutive Behavior for Quenching of Al–Cu–Mg Alloy With Consideration of Precipitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The deformation behavior of as-quenched 2024 Al–Cu–Mg alloy has been experimentally studied. The experiments are designed to cool specimens to the desired temperature with a constant cooling rate, i.e., 5 K/s. Isothermal ...
Using Simulated Annealing in a Bottleneck Optimization Model at Railway Stations
Publisher: American Society of Civil Engineers
Abstract: The bottleneck section of a railway passenger station is very complex, and many frequent technical and shunting operations are performed over a long time. The connection of station tracks, locomotive depots, and passenger ...
The Mechanism of Slip System Activation With Grain Rotation During Superplastic Forming
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The activated slip system of Ti-6Al-4V alloy during the superplastic forming (SPF) was investigated by the in-grain misorientation axes analysis (IGMA), and the mechanisms of slip system activation have been discussed. ...
Numerical Simulation of Diverting Fracturing for Staged Fracturing Horizontal Well in Shale Gas Reservoir
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hydraulic fractures are difficult to initiate simultaneously during multi-cluster fracturing owing to the strong heterogeneity of shale reservoir and the stress interference effect between adjacent hydraulic fractures. ...
A Modified Constitutive Model With Grain Rotation for Superplastic Forming of Ti–6Al–4V Alloy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A physically based constitutive model with internal state variables (ISVs) is established, it is used to describe the flow stress and microstructure evolution of Ti–6Al–4V alloy in the superplastic forming (SPF). The ISVs ...
