Effect of 17-4PH stainless steel powders interaction on feedstocks
Powder Technology, 2020Abstract The objective of this work is to investigate the effects of 17-4pH stainless steel powders interaction on properties of feedstocks. γ-aminopropyltriethoxy silane (KH550), γ-(2,3-epoxypropoxy)propyltrimethoxy silane (KH560), propyltrimethoxy silane (N313) were used to modify 17-4pH stainless steel powders, and described as KH550-m, KH560-m ...

Microstructures, properties, and applications of laser sintered 17‐4PH stainless steel
Journal of the American Ceramic Society, 2019Abstract 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,

Laser Cladding of 17-4PH Stainless Knife Edges
Volume 4: Cycle Innovations; Electric Power; Industrial and Cogeneration; Manufacturing Materials and Metallurgy, 2006Laser cladding of 0.4 mm and 0.8 mm wide knife edges made from 17-4PH stainless steel was investigated, using two types of powder and two different post heat treatments. Acceptable cladding deposits of 0.5 to 0.9 mm height were obtained on both sizes of knife edge, and with both powder types.

Failure Analysis of a 17-4PH Stainless Steel Part in an Exhaust Fastener
Journal of Failure Analysis and Prevention, 2021Despite 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.

Characterization of 17-4PH alloy processed by selective laser melting
Materials Today: Proceedings, 2017Abstract Additive manufacturing (AM) has revolutionized the way that engineering products are created through a simple concept of layer by layer addition of a part. Metallic components and its alloys have attracted worldwide attention due to the near net shape output and for the challenges posed in arriving at a high quality component.
