In spinal correction surgery, metallic rods are commonly bent intraoperatively by surgeons to conform to the patient-specific spinal curvature and are then fixed with pedicle screws. However, intraoperative rod contouring can introduce surface scratc...
The fatigue performance of reinforcing bars is essential to the durability and safety of reinforced concrete structures. BS 4449 assesses fatigue prequalification using a stress range of Δσ = 200 MPa, a stress ratio of R = 0.2, and a run-...
This study investigates the effect of Ti, Zr, and Hf microalloying on the microstructure, microhardness, tensile properties, and high-temperature performance of cast ML5 magnesium alloy. The alloy was modified with 0.05, 0.10, and 1.0 wt.% Ti, Zr, or...
This study quantifies the mechanical degradation caused by locally introduced rubber-glove contamination in stress-relieved PBF-LB/M Ti-6Al-4V. Rubber-glove fragments were inserted into defined build layers of standardized tensile specimens and into...
High-entropy alloys (HEAs) are characterized by having more than one principal element, in contrast to a traditional alloy with only one base element; this provides a much wider composition space compared to traditional alloys; hence, HEAs have been...
Molecular dynamics (MD) simulations were used to study the deposition and growth of Fe-Co-Ni-M-Al multi-component alloy films on a Si(100) substrate. By comparing the surface topography at incident energies of 0.1~0.5 eV, it was observed that an incr...
This study presents an integrated computational–experimental approach to enhance the tensile fatigue life of laser powder bed fusion (LPBF)-fabricated Ti-6Al-4V Gyroid scaffolds for orthopedic implants. Scaffolds with 60–80% porosity were...
High-entropy alloys (HEAs) show excellent mechanical properties, but their enormous compositional space makes experimental and computational exploration expensive. This study predicts the Vickers hardness (HV) of HEAs from nominal elemental compositi...
This study experimentally investigates the effect of oxide film thickness on the amplitude of laser-induced stress waves in AISI W1-7 carbon steel. Oxide layers of approximately 0.045 μm (straw-yellow) and 0.07 μm (blue) were synthesized via co...
