Fatigue Performance of Additively Manufactured Ti‐6Al‐4V: Impact of Different Kinds of Porosities, Surface, and Heat Treatments in Laser Powder Bed Fusion Productivity Parameters

Advanced Engineering Materials, EarlyView.
Ti‐6Al‐4V samples produced by laser‐powder bed fusion are tested for static and dynamic mechanical properties to systematically evaluate the effects of surface roughness and internal porosity when using productivity parameters. The most detrimental impact to fatigue is caused by surface roughness, lack of fusion and keyhole porosity in descending order.

Optimizing Laser Ablation of Stainless Steels for Volume Removal and Surface Quality Using Burst of Pulses

Advanced Engineering Materials, EarlyView.
This study explores the ablation efficiency and surface quality of laser‐treated stainless steel alloys (AISI 304, AISI 420, and AISI 316Ti) using an ultrashort pulsed laser and varying burst parameters (MHz, GHz, and Bi‐burst). Both ablation rates and surface quality parameters are determined, including isotropy surface roughness values, highlighting ...

Effect of Annealing Temperature on Microstructure and Dry‐Sliding Behavior of Powder Bed Fusion–Laser Beam Ti6Al2Sn4Zr6Mo Alloy

Advanced Engineering Materials, EarlyView.
Heat treatment parameters critically affect the wear resistance of powder bed fusion–laser beam (PBF‐LB)‐produced Ti–6Al–2Sn–4Zr–6Mo alloy. This study found that optimizing annealing temperature allows to obtain a tailored microstructure, which enhances the dry‐sliding behavior by forming a stable and functional mechanically mixed layer (MML), ensuring
