New Design of Copper–Inconel 601 Ground Electrode Spark Plug Based on a Thermo-Mechanical Model

Energies, 2020
Inconel 601 is one material of choice for intermediate- to high-temperature protective coatings for spark plugs’ ground electrodes. Production of ground electrodes of spark plugs implies the following operations: the tamping of the copper core in an ...

Impact of hydrogen on the high cycle fatigue behaviour of Inconel 718 in asymmetric push–pull mode at room temperature

, 2015
The influence of hydrogen on the high cycle fatigue (HCF) behaviour of Inconel 718 has been studied at room temperature in asymmetric push–pull mode using an ultrasonic HCF test rig. Fatigue tests have been carried out in gaseous hydrogen (GH2) and in Ar

Corrosion behavior and passive film properties of nickel-based alloy in phosphoric acid

Corrosion Communications, 2023
Corrosion behavior and passive film properties of nickel-based alloy (Inconel 625) in phosphoric acid were investigated, by means of a variety of electrochemical methods combined with surface analysis techniques. Results showed that Inconel 625 exhibited

Modelling Crack Growth in Additively Manufactured Inconel 718 and Inconel 625

Metals, 2023
This paper first examines crack growth in a range of tests on additively manufactured (AM) and conventionally manufactured Inconel 718. It is shown that whereas when the crack growth rate (da/dN) is plotted as a function of the range of the stress intensity factor (ΔK), the crack growth curves exhibit considerable scatter/variability, when da/dN is ...

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Analysis of machining performance of Inconel 718 printed by PBF-LM (powder bed fusion laser melting)

, 2021
Additive manufacturing based on powder bed fusion laser melting (PBF-LM) is receiving increased attention in nickel-base superalloys manufacturing, due to the difficulty of removal processes of superalloys.
