- Dynamic recrystallization of a wrought magnesium alloy: Grain size and . . .
The relationship among the average DRX grain size, temperature, and strain rate (Eq 8) revealed that the stress component (n) is 4 5 and the pre-exponent constant (C) is 86 when the activation energy (Q) is 164 kJ mol
- (PDF) Relationship between grain size and Zener-Holloman parameter . . .
The relationship between the resulting grain size and the applied working strain rate and temperature for the friction stir processing in AZ31 Mg is systemically examined The
- Friction Stir Welding Processing of Mg-Based Alloys: A Critical Review . . .
Friction stir welding (FSW) and friction stir processing (FSP) are two of the most widely used solid-state welding techniques for magnesium (Mg) and magnesium alloys Mg-based alloys are widely used in the railway, aerospace, nuclear, and marine industries, among others
- A Model to Predict the Resulting Grain Size of Friction-Stir-Processed . . .
To predict the resulting grain size of the processed material, two critical aspects have to be considered: grain refinement due to dynamic recrystallization and grain growth due to exposing the processed material to high temperature for a given period of time The proposed model begins by estimating the strain rate values from process parameters
- Microstructural simulation of friction stir welding using a cellular . . .
In this work, a finite element model (FEM) is established to study the microstructure evolution during friction stir welding (FSW) of AZ91 magnesium alloy To this aim, first, the hot compression tests at different temperatures and strain rates were carried out to achieve the flow stress curves
- The mechanisms of grain growth of Mg alloys: A review
Grain growth directly influences the plasticity and strength of Mg alloys As the grain size decreases from the microscale to the nanoscale, the plasticity of Mg alloys continually increases, whereas the strength first increases and later decreases
- Investigation and Modelling of Magnesium Alloy Grain Size during Hot . . .
In this study, we statistically analyzed the influence of the number of annealing treatments and the annealing holding time (5–20 min) between hot rolling passes on the microstructure of AZ31 alloy after four rolling passes and inter-pass annealing
- (PDF) Relationship between grain size and Zener–Holloman parameter . . .
The relationship between the resulting grain size and the applied working strain rate and temperature for the friction stir processing in AZ31 Mg is systemically examined The Zener–Holloman parameter is utilized in rationalizing the relationship
