    • Connection between mechanical relaxation and equilibration kinetics in a high-entropy metallic glass 

      Duan, Yajuan; Nabahat, Mehran; Tong, Yu; Ortiz Membrado, Laia; Jiménez Piqué, Emilio; Zhao, Kun; Wang, Yun-Jiang; Yang, Yong; Wada, Takeshi; Kato, Hidemi; Pelletier, J. M.; Qiao, Jichao; Pineda Soler, Eloi (American Institute of Physics (AIP), 2024-02-02)
      Article
      Open Access
      The slow transition from an out-of-equilibrium glass towards a supercooled liquid is a complex relaxation phenomenon. In this Letter, we study the correlation between mechanical relaxation and equilibration kinetics in a ...
    • Creep and recovery behavior of metallic glasses: a short review 

      Nabahat, Mehran; Duan, Yajuan; Xu, Zongrui; Qiao, Jichao; Pineda Soler, Eloi (2024-01)
      Article
      Open Access
      Due to the disordered structure of amorphous alloys, the complex structural dynamics involves the particle rearrangements with a large span in time and size scales. The characterization and mechanism of structural dynamics ...
    • Creep deformation in metallic glasses: a global approach with strain as an indicator within transition state theory 

      Zhang, LangTing; Wang, Yun-Jiang; Nabahat, Mehran; Pineda Soler, Eloi; Yang, Yong; Pelletier, Jean Marc; Crespo Artiaga, Daniel; Qiao, Jichao (Elsevier, 2024-03-01)
      Article
      Restricted access - publisher's policy
      Within the framework of transition state theory, the isothermal creep behavior of metallic glasses is elucidated through a unique global approach, where the topological state is exclusively linked to measured strain. Our ...
    • Delayed elasticity of metallic glasses: Loading time and temperature dependences of the anelastic relaxation 

      Nabahat, Mehran; Amini, Narges; Pineda Soler, Eloi; Yang, Fan; Qiao, Jichao; Ruta, Beatrice; Crespo Artiaga, Daniel (American Physical Society (APS), 2022-12-09)
      Article
      Open Access
      One of the hallmarks of disordered matter is the large amplitude of the anelastic deformation, i.e., the fraction of reversible deformation that is not instantaneously recovered after the release of load but is delayed in ...
    • PbS-Pb-Cu xS Composites for Thermoelectric Application 

      Li, Mengyao; Liu, Yu; Zhang, Yu; Han, Xu; Xiao, Ke; Nabahat, Mehran; Arbiol, Jordi; Llorca Piqué, Jordi; Alzate Ibáñez, Angélica María; Cabot, Andreu (2021-10-19)
      Article
      Open Access
      Composite materials offer numerous advantages in a wide range of applications, including thermoelectrics. Here, semiconductor-metal composites are produced by just blending nanoparticles of a sulfide semiconductor obtained ...
