Enhanced High-Temperature Mechanical Properties of Al–Cu–Li Alloy through T1 Coarsening Inhibition and Ce-Containing Intermetallic Refinement
Abstract
:1. Introduction
2. Materials and Methods
3. Results and Discussion
4. Conclusions
- (1)
- The thermal stability of Al–Cu–Li alloy is substantiality improved by Ce addition during thermal exposure at the medium-high-temperature stage (170 °C to 270 °C). The enhanced thermal stability of Ce-containing alloy can be attributed to the coarsening inhibition of T1 through impeding the diffusion of Cu. Ce segregates at the interface of the T1 phase can restrict its lateral growth, thereby inhibiting its coarsening.
- (2)
- As the test temperature increases from room temperature to 325 °C, the elongation of Ce-containing alloy increased rapidly from 7.5% to 17.5%, while that of Ce-free alloy only increased from 7% to 13%. The high tensile strength of Ce-containing alloy is always higher than that of Ce-free alloy. The high-temperature stable small Al8Cu4Ce phase in Ce-containing alloy can effectively pin dislocations and grain boundaries, which is beneficial to the improvement of the ductility and strength of the alloy in the high-temperature tensile test.
