Woven Eutectic Lamellar Structures Lead to Ultrahigh Strength and Energy Absorption Capacity in Additively Manufactured Lattice Structures

Small Structures, Volume 6, Issue 5, May 2025.
Herein, AlCoCrFeNi2.1 is selected to produce lattice structures by selective laser melting. The as‐printed lattice structures consist of numerous colonies of nanosized eutectic lamellar structures which are bent and interwind with each other to form a woven microstructure. The unique microstructure leads to unprecedented effective metal strength, yield

Distinctive transpassivation behavior and characteristics of passive films of laser powder bed fusion produced and annealed Ti–6Al–4V in Hank's solution

Journal of Materials Research and Technology
Passivated Ti alloys typically demonstrate enhanced corrosion resistance due to the formation of passive films. Intriguingly, in comparison to the annealed Ti–6Al–4V, laser powder bed fusion (LPBF) produced Ti–6Al–4V exhibits significantly attenuated ...

Computational Investigation on the Combined Effect of Applied Strain and Pore Configuration on Strain Concentrators in Additively Manufactured Metals

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Metal additive manufacturing (AM) provides a pathway for creating highly optimized components that would be difficult to produce using traditional manufacturing methods. However, regardless of printing parameters or postprocessing, porosity remains a prevalent challenge in AM components because strain concentrates in the vicinity of the pore ...

Influence of Ultrasonic‐Assisted Milling on Surface Integrity and Fatigue Strength of a Low Alloy Steel

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT The milling process significantly influences the surface integrity of metallic components through machining induced near‐surface residual stresses. Modern hybrid machining processes, such as ultrasonic‐assisted milling (USAM), offer the potential to induce beneficial near‐surface compressive residual stresses compared to the near‐surface ...

Rehabilitation in Cases of Maxillary Lateral Incisor Agenesis Using Zirconia Implant and Abutment: Finite Element Analysis and Systematic Review

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective The use of narrow‐diameter implants has emerged as a strategy to compensate for the reduced bone dimensions of maxillary lateral incisor agenesis (MLIA). This study integrates finite element analysis (FEA) and systematic review (SR) to assess the biomechanical and clinical viability of implant‐supported crowns in MLIA scenarios ...

The effects of anodization and instrumentation on titanium abutment surface characteristics and biofilm formation

Journal of Prosthodontics, EarlyView.
Abstract Purpose To assess the impact of anodization and instrumentation on titanium abutment surface characteristics (surface roughness and wettability) and biofilm formation (viability and mass). Materials and Methods Titanium discs were obtained from pre‐milled abutment blanks made of titanium‐6aluminum‐7niobium alloy.
