Study on the microstructure evolution and deformation strengthening mechanism of aluminum-magnesium alloys under continuous deformation
Source abstract
Abstract
This study delves into the strengthening deformation mechanism of secondary phase evolution in 5356 aluminum alloy wires after multiple consecutive stretching processes. Detailed structural properties after different stretching channels were analyzed using Electron Backscatter Diffraction (EBSD) and Transmission Electron Microscopy (TEM). Additionally, the decomposition process of the secondary phase under conditions of extensive plastic deformation was thoroughly investigated. The results indicate that after drawing four passes, grain refinement was observed, and the hard and brittle Al13Fe4 phase at grain boundaries fragmented into smaller particles, which were distributed throughout the matrix, significantly enhancing the strength and ductility of the alloy. The <111> texture was determined to exhibit significant stability during the deformation process, and the strengthening mechanisms' impact on material properties was quantitatively analyzed.
