INCONEL@ alloy 625 is a nickel-chromium-molybdenum alloy that is used for its high strength, excellent fabricability and weldability, and outstanding corrosion resistance. The outstanding and versatile corrosion resistance of INCONEL alloy 625 under a wide range of temperatures and corrosive environments is the primary reason for its wide acceptance in chemical processing and other applications...

Size, shape, volume fraction and distribution of embedded g/ phase in g phase has direct effect on strength of INCONEL alloy. Microstructure parameters of INCONEL phases are quantified from microstructure images using transmission electron microscopy (TEM). Different TEM sample preparation techniques were used to study INCONEL 738 alloy microstructure for transmission electron micros...

Superplasticforming (SPF) has become an important manufacturing method for aerospace and fuselage components. The basic reasons for the popularity of this process are reviewed and the compatibilityoffine-grained INCONELB alloy71 8SPF@ to superplasticforming are presented in this paper. The temperature limitations of current aluminum and titanium alloys employed in SPF parts for gas turbine comp...

Article history: Received 2 January 2015 Received in revised form 22 October 2015 Accepted 23 October 2015 Available online 27 October 2015 The hot deformation behaviour of Inconel alloy IN718 was studied in the temperature range of 950–1100 °C and at strain rates of 0.01 and 1 s with a view to understand the microstructural evolution as a function of strain rate and temperature. For this purpo...

Dynamic strain aging (DSA) and jerky flow phenomena in the commercial Ni-base alloys Inconel 600 and 690 have been investigated. Tensile tests were performed in the strain rate range of 10 to 10 s at temperatures of 100 – 600 C. No remarkable difference in the DSA behaviour of Inconel 600 and 690 alloys was observed. Tensile properties of the studied alloys in the DSA temperature range, and typ...

Vertically aligned arrays of multi-wall carbon nanotubes (MWNT) are grown on Inconel 600, a nickel-based super-alloy. Using x-ray photoelectron spectroscopy (XPS) and chemical vapor deposition (CVD) growth of the MWNTs it is shown that a stable oxidation barrier is required for the stabilization of iron on the substrate and subsequent nanotube growth. This evidence for passivation oxide support...

Experimental results on hot deformation and dynamic structural processes of nickel based alloy Inconel 718 are reviewed. The focus is the analysis of dynamic precipitation processes which operate during hot deformation of these materials at elevated temperatures. Hot compression tests were performed on the solution treated precipitation hardenable nickel based superalloy Inconel 718 at 720-1150...

INCONEL alloy 783 was annealed and aged following the standard heat treatment procedure. One set of specimens was then isothermally exposed at 500 degrees C for 3000 h. Mechanical properties were measured at room temperature and 650 degrees C, and the results showed the prolonged exposure increased the strength and decreased elongation of alloy 783. The microstructures of as-produced and expose...
