Creating constitutive models of the DRX process in various Mg … WebApr 1, 2024 · The dynamic recrystallization (DRX) process and grain structure evolution during friction stir welding determine the final microstructure and performance of weld joints. In this study, Monte Carlo method is applied to develop a model for numerical simulation of dynamic recrystallization in friction stir welding of aluminum plates. An ...
WebDynamic recrystallization (DRX) is the most significant metallurgical phenomenon during friction stir welding (FSW) and friction stir processing (FSP). In order to simulate the microstructure ... WebThe results showed that the dynamic recrystallization (DRX) occured during the hot compression processing from the strain-stress flow curves. When the temperature increased to 420 °C, the average grain size reduced to 6.64 μm, and the volume fraction of DRXed grains increased to 81.5%. All the compressed alloys exhibited a typical compression ...
WebApr 11, 2024 · On the other hand, dense arrangements of LPSO decrease the volume fraction of dynamic recrystallization (DRX). Dilute Mg–Zn–Y alloys tend to form stacking faults rather than a single type of LPSO, resulting in alternating soft and hard phases, which is referred to as a Mille-feuille structure (MFS) [23,24]. Hagihara et al. claimed that a ...
