As one of the most important high-specific-strength structural materials, duplex (α+β) Ti alloys exhibit a broad range of mechanical properties by tailoring their major constituent-HCP α phase. However, high-strength duplex Ti alloys often confront low work hardening rate (WHR, Θ) and thus the limited uniform elongation (εu), due to the following two factors. i) The HCP α-phase often lack...

​Metallic glasses, also known as amorphous alloys, exhibit superior mechanical properties such as high strength and elasticity due to their disordered atomic arrangement. However, these properties also render them prone to the formation of localized shear bands at the nanoscale during plastic deformation. The initiation and propagation of these shear bands often trigger brittle fracture, which...

​The high yield strength and tensile plasticity of metallic materials are crucial for their engineering applications. However, for all the alloys developed thus far, including recent high-entropy alloys, those possessing good tensile ductility rarely approach 2 GPa yield strength at room temperature. The few that do are mostly ultrastrong steels; however, their stress-strain curves exhibit pla...

Under the strong impetus of China’s “dual carbon” (carbon peak and carbon neutrality) strategy, renewable and clean energy sources such as wind and solar power are developing rapidly and are expected to play a central role in the nation’s future energy landscape. However, the inherent intermittency and variability of these sources, influenced by uncontrollable natural conditions, present si...

​Water electrolysis is a key technology for producing green hydrogen energy, but its efficiency is limited by the sluggish oxygen evolution reaction (OER) kinetics at the anode. Studies have shown that the intrinsic reaction barrier stems from the spin-state transition from singlet H₂O/OH⁻ to triplet O₂. However, effective strategies to regulate the spin states of OER catalysts remain scarc...

A research team led by Professors Tai Min and Tao Li at Xi’an Jiaotong University (XJTU) has achieved a major breakthrough in the experimental realization of electric field control of magnetism in two-dimensional (2D) van der Waals multiferroic heterostructures. Their work, focusing on Fe₃GaTe₂/CuInP₂S₆ heterostructures, for the first time, demonstrates stable, nonvolatile electric modulat...

Porous silicon carbide (SiC) ceramics exhibit unique advantages in high-temperature insulation, corrosive gas filtration, and lightweight structural applications due to their low density, exceptional thermal stability, corrosion/oxidation resistance, and so on. However, their inherent brittleness—combined with the tendency of pores to act as crack initiation sites—often results in low strengt...

Magnetic materials play a crucial role in spintronics and its applications. Beyond traditional ferromagnetic systems, antiferromagnets have attracted growing attention in the fields of condensed matter and materials physics in recent years, owing to their unique advantages such as ultrafast spin dynamics, precise control schemes, absence of stray magnetic fields, and robustness against external...
