    Design of a novel Cu-Cr-X alloy with high strength and high electrical conductivity based on mechanical learning by Yunqing Zhu, Yicheng Cao, Lijun Peng, Qian Yu, Zhen Yang, Zengde Li, Junsheng Wu, Haofeng Xie

    Published 2025-02-01
    “…The Cu-Cr-Zr-Mg-Ti alloy with superior properties was optimally designed by genetic algorithm from the massive solutions, which the experimental tensile strength and conductivity reached 668 MPa and 71.5 %IACS, respectively. The atom probe tomography results show that Zr, Mg, and Ti simultaneously segregated in the Cr-rich phase after aging at 440 °C for 480 h, which significantly improves the stability of the precipitated Cr phase and inhibited the Cr-rich phase transition from fcc to bcc structure. …”

    Mixing-enthalpy modulation on phase transformation in the gradient chemical core/shell high-entropy shape-memory alloys by E-Wen Huang, Tu-Ngoc Lam, Zachary H. Aitken, Mao-Yuan Luo, Nien-En Chiang, Yuh Sun, Jo-Chi Tseng, Ching-Yu Chiang, Wan-Zhen Hsieh, Wen-Jay Lee, Yong-Wei Zhang, Peter K. Liaw, Che-Wei Tsai

    Published 2025-03-01
    “…The dendritic microstructure in Cu15Ni35Ti20(HfZr)30 exhibits the mixing enthalpy-driven pronounced composition inhomogeneity of an Ni-Hf-rich core and Cu-Zr-Ti-rich shell, demonstrated by thermodynamics calculations and second nearest-neighbor modified embedded atom method (2NN MEAM) formalism. The shell acts as an interfacial energy barrier for the stable martensitic transformation that occurred primarily in the effective Ni-Hf-rich core of the Cu15Ni35Ti20(HfZr)30. …”
