The prediction of the equilibrium and metastable morphologies during solidification Ni-based superalloys on mesoscopic scale can be performed using phase-field modeling. In present paper, we apply model to simulate evolution microstructures depending undercooling in a quasi-binary approximation. results modeling are compared with experimental data obtained samples alloy Inconel 718 (IN718) proc...

MAX phases (M = transition metal, A = A-group element, and X = C/N) are of special interest because they possess a unique combination of the advantages of both metals and ceramics. Most attention is attracted to the ternary carbide Cr2AlC because of its excellent high-temperature oxidation, as well as hot corrosion resistance. Despite lots of publications, up to now the influence of bias voltag...

Selective laser melting (SLM) has been applied to manufacture various alloy components with excellent properties, but its further application is restricted by the intrinsic defects. In this work, internal defect distributions in samples of three alloys (316L stainless steel, AlSi10Mg and Inconel 718) were investigated respectively, considering effects geometrical characteristics samples. The de...

Nickel-based superalloys exhibit excellent high temperature strength, corrosion and oxidation resistance creep resistance. They are widely used in applications aerospace, power petrochemical industries. The need for economical efficient usage of materials often necessitates the joining dissimilar metals. In this study, welding between two different nickel-based superalloys, Inconel 718 600, was...

Inconel 718 alloy which was prepared using selective laser melting (SLM) forming technology underwent various annealing treatments. Optical microscope, scanning electron backscattered diffraction and MTS testing machine were used to study the microstructure, mechanical fatigue properties of melted by under different The results show that microstructure after homogenization doubleaging is most o...

An experimental study has been performed to investigate the capabilities of dry, conventional and high pressure jet assisted turning of two different hard-to-machine materials, namely hard-chromed and surface hardened Ck45 and Inconel 718. The capabilities of different hard turning procedures are compared by means of chip breakability, technological windows, cooling lubrication efficiency, and ...

Since the cutting tools used in machining process of super alloys are subjected to high cutting forces, accordingly tools life is reduced, therefore improvement in alloys machining and reducing cutting forces to achieve longer tools life is an essential necessity. In this research, the effect of changes in feed rate on cutting forces in machining process of nickel based super alloys is investig...

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...

A new post-weld heat treatment (PWHT) cycle was designed for novel dissimilar linear friction welding (LFW) of selective laser melted (SLM) Inconel 718 (IN718) to AD730 forged nickel-based superalloy. The microstructure and hardness the joints after PWHT are investigated compared with those as-linear welded samples. precipitation γ′ + γ″ is determined as main mechanism increase mechanical prope...
