The Al–Cu–Li alloy has poor plasticity and hot workability, making it difficult to form by single-pass working, so the multi-stage thermomechanical processing is usually required. However, there is a general distinctly heterogeneous fiber structure in deformed alloys, which has non-negligible effects on the stability and formability of subsequent d...

The mechanical properties and microstructure evolution of the spray formed 2195 Al-Li alloy extruded sheet at warm forming temperatures (100°C-300°C) were systematically investigated in this work. The results showed that the yield strength and ultimate tensile strength of the alloy declined obviously as the temperature rose, while the elongation in...

Dynamic recrystallization (DRX) is one of the more convenient and effective means of refining grains during hot deformation, which is closely related to the precipitation behavior. Three alloys with varying pre-precipitations are designed by carrying out different heat treatment processes to explore the effects of precipitation on the recrystalliza...

Accurate prediction of the texture evolution of aluminium alloys during hot extrusion process plays an important role in the die design and determination of process parameters. In this work, the deformation texture of aluminium alloys under three-dimensional deformation path are investigated numerically and experimentally. Firstly, the extrusion pr...
