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,

Investigation of powder size effects on sintering of powder injection moulded 17-4PH stainless steel

Powder Metallurgy, 2017
Densification behaviours of 17-4PH stainless steel powders (SUS17-4PH) of three different particle sizes during the sintering were investigated. The samples with different mean particle sizes of 3.17, 4.22 and 8.30 mu m were prepared through powder ...

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.

Inhibitive Effect of Nitrate on Pitting Corrosion of 17-4PH Stainless Steel

Corrosion, 2016
In this work, the inhibition effect of nitrate on the pitting corrosion of 17-4PH stainless steel was investigated in the chloride solution. Potentiodynamic and potentiostatic techniques were used to measure the pitting potential and induction time in various concentrations of chloride and nitrate ions.
