Failure Analysis of a 17-4PH Stainless Steel Part in an Exhaust Fastener

Journal of Failure Analysis and Prevention, 2021
Despite high level of attention in the process of making metallic fasteners, failure of the fasteners happens in various industries. Sometimes, failures are recognized during the quality control checks in the companies. During a batch of production and during assembly test, failure of a 17-4PH stainless steel part in an exhaust fastener was seen.

Microstructures, properties, and applications of laser sintered 17‐4PH stainless steel

Journal of the American Ceramic Society, 2019
Abstract The effects of hot isostatic pressing (HIP) on the densification, mechanical properties, and microstructures of laser‐powder bed fusion (L‐PBF) 17‐4 PH stainless steel parts were studied using gas‐ and water‐atomized powders. The % theoretical density, ultimate tensile strength, yield strength, elongation,

Microstructure and hardness investigation of 17-4PH stainless steel by laser quenching

Materials Science and Engineering: A, 2012
Abstract Surface hardening of 17-4PH was achieved by laser transformation hardening using 5 kW continuous wave CO 2 laser system. The microstructure of the laser-quenched sample was investigated by optical microscopy, transmission electron microscope and 57 Fe Mossbauer spectrometer. The hardness profile was determined by a Vickers hardness tester.

Experimental investigation on selective laser melting of 17-4PH stainless steel

Optics & Laser Technology, 2017
Abstract Selective laser melting (SLM) is an additive manufacturing (AM) technique that uses powders to fabricate 3Dparts directly. The objective of this paper is to perform an experimental investigation of selective laser melted 17-4PH stainless steel. The investigation involved the influence of separate processing parameters on the density, defect,

Effect of ECAP on the Microstructure and Mechanical Properties of 17-4PH Stainless Steel

Materials Science Forum, 2010
Experiments were conducted to evaluate the influence of equal-channel angular pressing (ECAP) on the microstructure and mechanical properties of 17-4PH steel. The 17-4PH steel was solution-treated at 1040°C for 1h followed by oil cooling before ECAP process.
