Effect of Ni3Nb precipitation on the corrosion resistance of Inconel alloy 625
Journal of Materials Science Letters, 1990Alloy 625 is susceptible to precipitation of Ni 3 Nb upon exposure to temperatures in the range of 650 to 870°C. Since this phase is low in chromium content as shown later, it can be expected to degrade the chemical stability of the alloy in oxidizing media.

Corrosion Resistance of Additively Manufactured 625 Inconel Alloy in Seawater
ECS Meeting Abstracts, 2018Additive manufacturing (AM) of metals and metal alloys offers advantages of fast and flexible design of parts of various shapes, and low-waste operation. AM manufacturing of metals/alloys involves building materials layer-by-layer from a metal/alloy powder. The powder in each layer is melted by a high intensity laser or electron beam, and individual

Experimental Investigations on Inconel 625 Alloy Using Plasma Arc Machining
International Journal of Manufacturing, Materials, and Mechanical Engineering, 2020Plasma arc machining (PAM) is a non-traditional machining process widely used to machine intricate part profiles for alloys that are difficult to machine. The Burr height, Kerf ratio, and material removal rate (MRR) are predominant factors that influences the performance and quality of plasma cut surfaces.

Effect of niobium on marine crevice corrosion resistance of Inconel alloy 625
British Corrosion Journal, 1987Abstract The crevice corrosion resistance of Inconel alloy 625 has been investigated as a function of its niobium content. A technique used primarily for mathematical modelling of crevice corrosion in chloride media has been used to compare the probable resistances to this type of corrosion.

Effectiveness of Cryogenic Cooling in Turning of Inconel 625 Alloy
2018The present study is to investigate the role of cryogenic cooling using liquid nitrogen as coolant on the tool wear and surface roughness in turning of Inconel 625 with PVD-TiAlN-coated carbide inserts. The machining parameters of the experimental works were cutting conditions (dry and cryogenic cooling), cutting speeds (43, 71, 118 m/min), feed rate ...

Corrosion Behavior of Inconel 625 Alloy in Na2SO4–K2SO4 at High Temperature
2019The corrosion behavior of Inconel 625 alloy at 800 and 900 °C in the molten salt of 75 wt% Na2SO4–25 wt% K2SO4 was studied. The corrosion mechanism of Inconel 625 alloy after hot corrosion is mainly alkaline melting mechanism. The Cr2O3 on the surface of the alloy dissolved in molten salt as Na2CrO4, leading to the loss of the protective oxide layer on

Magnetic Susceptibility of Inconel Alloys 718, 625, and 600 at Cryogenic Temperatures
1990In June 1988, the Discovery Space Shuttle mission was delayed because of a malfunctioning hydrogen fuel bleed valve system. The problem was traced to the linear variable differential transformer (LVDT) which produced erroneous readings for the valve position.
