Titanium (Ti), characterized by its exceptional mechanical properties, commendable corrosion resistance and biocompatibility, has emerged as the principal functional materials for implants in biomedical and clinical applications. However, the Ti-6Al-4V (TC4ELI) alloy has cytotoxicity risks, whereas the strength of the existing industrially pure titanium TA4 is marginally inadequate and will significantly limit the scenarios of medical implants. Herein, we prepared ultrafine-grained industrial-grade pure titanium TA4 and titanium alloy TC4ELI via the equal channel angular pressing method, in which the TA4-1 sample has ultrahigh strength of 1.

- Researchers developed a high-performance hafnium (Hf) cathode for air/water vapor plasma torches using density functional theory (DFT) to guide the design process.
- A quasi-nanocrystalline hexagonal close-packed (HCP) Hf-LaO cathode was fabricated via powder metallurgy, showing a thermal emission current density approximately 20 times greater than conventional Hf cathodes and a significantly extended lifespan.
- The manufacturing process for the Hf-LaO cathodes is simple, requires few doped oxides, and is cost-effective, leading to better performance than traditional Hf melting methods without major cost increases.
