In this study, the effect of severe plastic deformation during friction stir back extrusion of Al-Cu-Mg alloy with different amounts of Li microalloying on microstructure, mechanical properties, and corrosion resistance was investigated. The Cu:Mg ratio in the Al-Cu-Mg alloy was 3.8. The results show that regardless of the amount of lithium microalloying added in the Al-Cu-Mg alloy, a significant change in the size of the dendrites, as well as the amount of secondary phase particles, and the eutectic structure formed in the inter-dendritic space, is not visible. Although with the increase of lithium percentage up to 0.5 wt.%, a slight decrease in grain size is observed in the central area and surface areas of the extruded wires, the difference in the average grain size in the three samples is not large. As the amount of lithium increases, the amount of lithium in the structure of S-Al2CuMg precipitates increases, and finer precipices are formed. By adding 0.5 wt.% of lithium, the evidence shows that the corrosion resistance has increased by 35 %. It is also observed that the corrosion potential decreases by 7 % with the increase of lithium percentage up to 0.5 wt.%.

“…Compared to CMCs, alloys have the disadvantage of being prone to precipitation roughening, leading to a loss of strength [ 9 ]. Therefore, CMCs have received much attention from researchers and are considered to be highly promising materials for advanced electrical applications [ 10 ]. The choice of reinforcing phase is extremely important in the preparation of CMCs.…”

Among the various reinforcement phases available in Cu-based composites, the unique layered structure and easy diffusion of A-layer atoms make MAX phases more suitable for reinforcing a copper matrix than others. In this study, Cu-coated Ti3AlC2 particles (Cu@Ti3AlC2) were prepared through electroless plating, and Cu@Ti3AlC2/Cu composites were fabricated via vacuum hot-press sintering. The phase composition and microstructure of both Cu@Ti3AlC2 powder and composites were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The results demonstrate the creation of successful electroless copper plating to obtain a Cu coating on Ti3AlC2 particles. At 850 °C, a small amount of Ti3AlC2 particles decompose to form TiCx, while Al atoms from the A layer of MAX phase diffuse into the Cu matrix to form a solid solution with Cu(Al). The test results reveal that the density of the Cu@Ti3AlC2/Cu composite reaches 98.5%, with a maximum compressive strength of 705 MPa, which is 8.29% higher than that of the Ti3AlC2/Cu composite. Additionally, the compressive strain reaches 37.6%, representing an increase of 12.24% compared to that exhibited by the Ti3AlC2/Cu composite.

“…Titanium matrix composites (TMCs) are extensively utilized in the aerospace and automotive industries due to their exceptional corrosion resistance, high temperature resistance, and mechanical properties [1][2][3]. (TiB + TiC)/TC4 is a typical TMC, and relevant studies [4] have indicated that the composite has the best combination of strength, modulus, and plasticity by introducing TiB and TiC simultaneously.…”

The hot deformation behavior of titanium matrix composites plays a crucial role in determining the performance of the formed components. Therefore, it is significant to establish an accurate constitutive relationship between material deformation parameters and flow stress. In this study, hot compression experiments were conducted on a (2.5 vol%TiB + 2.5 vol%TiC)/TC4. The experiments were performed under temperatures ranging from 1013.15 to 1133.15 K and strain rates ranging from 0.001 to 0.1 s−1. Based on the stress–strain data obtained from the experiment, the constitutive models were established by using the Arrhenius model and the BP neural network algorithm, respectively. Considering the relationship between strain rate, hot working temperature, and flow stress, a comparative analysis was conducted to evaluate the prediction accuracy of two different constitutive models. The research results indicate that the flow stress of (2.5 vol%TiB + 2.5 vol%TiC)/TC4 increases with decreasing temperature and increasing strain rate, and the stress–strain curve shows obvious work hardening and softening behaviors. Both the Arrhenius model and the BP neural network algorithm are effective in predicting the hot compression flow stress of (2.5 vol%TiB + 2.5 vol%TiC)/TC4, but the average relative error and root mean square error of the BP neural network algorithm are smaller and the correlation coefficient is higher, thus possessing higher accuracy and reliability.
