This study focuses on a novel <i>β</i>-rich <i>α</i> + <i>β</i> titanium alloy, Ti-6Al-4 V-2Mo-2Fe (Ti6422), and conducts the first systematic investigation based on powder metallurgy processing, with emphasis on elucidating the regulatory mechanism of aging cooling rate on microstructural evolution and synergistic strength-plasticity performance. The results show that the heat treatment protocol involving solution treatment at 850°C for 2 h and aging at 600°C for 6 h followed by furnace cooling (FC) enables the alloy to achieve exceptional comprehensive mechanical properties: ultimate tensile strength of 1405 MPa, yield strength of 1339 MPa, and elongation of 10.2%.

The weight loss per area increased with the increasing temperature, which intuitively reflects the enhancement of the oxidation intensity of the steel at high temperatures. The value of activation energy (Ea) was 124.82 KJ/mol for the 10CrNi3MoV steel through the determination of non-isothermal oxidation kinetic. The isothermal oxidation kinetic had been studied from 900°C to 1200°C for 720 min.

In addition, the thickness of the oxide film formed by outward transfer diffusion was larger than that by inward transfer diffusion, which indicated outward transfer diffusion of iron ions mainly controlled the oxidation mass transfer during the high-temperature oxidation reaction.

This thermally-activated transition of crack morphology was clearly captured by incorporating the orientation-dependent slip laws and cohesive surface energies into the CPFEM-CZM modeling, after calibration with the experimental load–displacement data. Successful validation of the CPFEM-CZM model allows detailed extraction of the plastic work and cohesive surface energy from individual crack surfaces, and provides a physical- and indentation-based method for measuring fracture toughness from materials with anisotropic plasticity and fracture. The complicated interplay between plasticity and fracture at the nanoscale can be understood mechanistically using such techniques, which aligns well with the theme of this special edition on bridging the length scale effects in mechanical testing.

The results indicated that the leaching process was initially impeded by the common ion effect; this inhibition was effectively alleviated by increasing the L/S ratio. Under optimized conditions of 3 N acid concentration, 110°C, an L/S ratio of 25 mL/g, and a duration of 60 min, the aluminum leaching efficiency exceeded 99%, thereby avoiding the generation of secondary solid hazardous waste.
