Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Adhesiveness of TiO2 PVD coating on electropolished stainless steel 17–4 PH orthodontic bracket

Materials Research Express, 2019
Performance of stainless steel 17-4 PH as the orthodontic bracket can be improved by titanium dioxide (TiO _2 ) coating. In order to produce a good quality of the coating layer, the substrate had to be smooth and free from any contaminants.

Morphology, Transport, and Dynamics of Protein Adsorption in Open‐Cell Metal Foam

Advanced Engineering Materials, EarlyView.
Stainless steel (SS) open‐cell foams are shown to adsorb more protein per unit area than previously reported 316L SS and chromium oxide surfaces under static and flow conditions. An integrated approach combining 3D pore imaging, flow simulation, and protein adsorption experiments characterizes the foam’s performance.

Normalizing Effect of Heat Treatment Processing on 17-4 PH Stainless Steel Manufactured by Powder Bed Fusion

Metals, 2022
Laser powder bed fusion (L-PBF)-processed 17-4 PH stainless steel (SS) generally exhibits a non-equilibrium microstructure consisting mostly of columnar δ-ferrite grains and a substantial fraction of retained austenite and martensite, contrary to 17-4 PH

Hybrid Laser-arc Welding of 17-4 PH Martensitic Stainless Steel [PDF]

Lasers in Manufacturing and Materials Processing, 2015
PH stainless steel has wide applications in severe working conditions due to its combination of good corrosion resistance and high strength. The weldability of 17-4 PH stainless steel is challenging. In this work, hybrid laser-arc welding was developed to weld 17-4 PH stainless steel.

Effect of surface preparation on the corrosion of austenitic stainless steel 304L in high temperature steam and simulated PWR primary water [PDF]

, 2012
The corrosion behavior of 304L grade stainless steel (SS) in high-temperature steam and in a simulated Pressurized Water Reactor (PWR) is studied. The goal was to characterize the nature of the oxide coating generated during 500 h exposure of samples in ...

Electrodeposition in Structural Lattices of Variable Architectures

Advanced Engineering Materials, EarlyView.
Electrodeposition enables geometry‐sensitive, autonomous void filling while simultaneously tuning chemical and mechanical properties. The development of approaches that can autonomously fill and heal material voids and yield composites with tailorable properties is increasingly relevant in engineering.

Enhancement in hardness and corrosion resistance of directed energy deposited 17–4 PH martensitic stainless steel via heat treatment

Journal of Materials Research and Technology, 2023
Directed energy deposition (DED) process involves complex cyclic reheating and rapid cooling, which probably lead to differences in microstructure and corrosion resistance from the wrought alloys. In the present study, the pitting corrosion resistance of

Hot Deformation and Dynamic Recrystallization of 17-4 PH Stainless Steel

ISIJ International, 2013
)The hot deformation behavior of a 17-4 PH stainless steel was investigated by compression tests. Thetypical single-peak dynamic recrystalization (DRX) behavior and also a transition state between single andmultiple peak (cyclic) behaviors were seen in the resultant flow curves.
