Embrittlement of laser surface-annealed 17-4 PH stainless steel
Materials Science and Engineering: A, 2001Abstract Stress corrosion cracking and fatigue crack growth behavior were determined in 17-4 PH stainless steel under various metallurgical conditions, including the H900 (482°C/1 h), H1025 (552°C/4 h) aging and laser surface annealing treatments. Peak-aged (H900) specimens locally irradiated by laser beam consisted of a portion of composite region ...

Impact properties of sintered and wrought 17–4 PH stainless steel
Powder Metallurgy, 2006Charpy V notch (CVN) impact testing was conducted on full size and subsize specimens of sintered and wrought 17–4 PH stainless steel (17–4 PH SS) in the as sintered and H900 heat treated conditions. Test geometries correspond to the American Society for Testing and Materials (ASTM) and Metal Powder Industries Federation (MPIF) impact testing standards.

Practical Aspects of Plasma Nitriding Kinetics for 17-4 PH Stainless Steel
AM&P Technical Articles, 2022Abstract Plasma nitriding is very effective in removing the passive layer of chromium oxide formed naturally on the surface of stainless steel, but controlling the kinetics is key for optimal results.

Characterization of Electron Beam Welded 17-4 PH Stainless Steel
Canadian Metallurgical Quarterly, 2008AbstractThe Canadian Department of National Defence (DND) currently has a requirement for a fully automated captive trajectory system (CTS) with six degrees of freedom, all of which are to be motorized, to study the movement of stores (such as missiles) during carriage/release testing of F-18 and other military aircraft in the National Research Council

Microstructure of the heat‐affected zone in 17–4 PH stainless steel
Steel Research, 1989The microstructure of the heat‐affected zone (HAZ) in bead‐on‐plate welded 17–4 PH stainless steel was studied with special reference to the roles of prior heat treatment and heat input during welding. The HAZ in solution‐annealed condition consists of three different microstructural zones containing: (i) retransformed martensite and reformed austenite;

Production and aging of highly porous 17-4 PH stainless steel
Journal of Porous Materials, 2011This study describes production of highly porous 17-4 PH stainless steel for biomedical implant applications by space holder-sintering technique. 17-4 PH stainless steel powders were mixed with space holder and then compacted. For designing pore properties, both spherical and irregular shaped carbamide with different particle size ranges were used as ...

Pitting Behavior of Type 17-4 PH Stainless Steel Weldments
Corrosion, 1995Electrochemical methods of measuring pitting potentials (Epit) were used to study the pitting resistance of type 17% Cr-4% Ni (17-4, UNS S17400) precipitation hardenable (PH) stainless steel (SS) weldments. The main objectives were to evaluate the pitting resistance of the base metal, the heat-affected zone (HAZ), and the weld metal portions of 17-4 PH

A study of tensile behavior of SLM processed 17-4 PH stainless steel
Materials Today: Proceedings, 2021Abstract This study provides an insight into the comparison of the tensile properties between 17-4 PH SS samples processed by Selective Laser Melting (SLM) and the wrought 17-4 PH samples. The tests were conducted according to the international standard ASTM E8 and the microstructural studies were also performed.

Embrittlement Fracture in a 17-4 PH Stainless Steel after Aging at 400°C
Materials Science Forum, 2005The embrittlement fracture mechanism caused by microstructural evolution of 17-4 PH stainless steel at long term aging was studied using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The solution treated specimen consists largely of lath martensite with a small fraction of elongated δ-ferrite.

Fatigue Behavior of Laser Metal Deposited 17-4 PH Stainless Steel
2020As additive manufacturing (AM) technology has evolved, its use has been extended to address more challenging service loading and environmental applications. To ensure broader acceptance of AM technology and to justify its use in routine production, there is a need to characterize the mechanical properties of AM parts.
