Despite these merits, its practical utilization faces challenges stemming from substantial volume fluctuations and limited electronic conductivity. To tackle these issues, a plum-branch-like structure of CoSe2@N-doped carbon that embedded in one-dimensional N-doped carbon fibers (CoSe2@NC/CFs), is successfully synthesized through an in-situ confinement method. Well-defined CoSe2@NC nanoparticles, featuring diameters between 20∼30 nm, are uniformly dispersed on both the inner and outer surfaces of the carbon fibers. The distinctive architecture of CoSe2@NC/CFs ensures an increased number of active sites, elevated electronic conductivity, alleviated volume expansion, and accelerated reaction kinetics. Consequently, the CoSe2@NC/CFs exhibits remarkable cycling performance and exceptional rate capability. Operating at a current density of 1000 mA g−1, the CoSe2@NC/CFs anode sustains a capacity of 664 mA h g−1 with no obvious capacity decay over 500 cycles. Even at a high current density of 5000 mA g−1, it maintains a capacity of 445 mA h g−1 with a mere 0.02 % capacity decay per cycle.

However, achieving a good combination of dissimilar alloys with different mechanical properties has always been a research difficulty. In this work, a Ti600/Ti2AlNb joint was fabricated through electron beam welding and an isothermal forging was used to optimized its microstructure and mechanical performance. The isothermal forging process increases the ultimate tensile strength (UST) and yield strength (YS) of the Ti600/Ti2AlNb joint by ∼18 %, while ∼2.5 times the ductility. It is indicated that before forging, the Ti600/Ti2AlNb joint exhibits a much lower strength than that of Ti600 matrix, whereas the opposite is true after isothermal forging. The isothermal forging broken the coarse columnar grains of Ti600/Ti2AlNb joint and render to an equiaxed B2 structure in which the acicular α2 and O phase are precipitated, resulting a synchronous enhancement of strength and ductility.
