In this study, the flow characteristics and behaviors of virgin and recycled Inconel powder for
powder-bed additive manufacturing (AM) were studied using different powder …

In the present study, selective laser melting (SLM) was used to successfully fabricate Inconel
718–tungsten carbide (WC) composites. The processing parameter optimization results …

This study presents incremental finite element computations of creep‐fatigue crack growth in
Alloy 718 at 65 0° C in air. Alloy 718 is representative of creep‐brittle materials, in which …

Thermomechanical fatigue (TMF) crack growth of Alloy 718 when the cycle includes long
high‐temperature tensile dwells is often accelerated because sustained‐load crack growth …

The present paper summarizes experimental work to identify the mechanisms of dwell-time
cracking during service operation of polycrystalline nickel-base superalloys, such as Alloy …

The crack growth behaviour of Direct Aged Inconel 718 was studied at 550° C. Experiments
were carried out under pure fatigue cycles, hold-time cycles of different durations and a mix …

High temperature materials subjected to elevated temperature have been shown to be
sensitive to dwell times, giving an increased crack growth rate. The interaction between …

The computational efficiency in analysing cyclically loaded structures is a highly prioritised
issue for the gas turbine industry, as a cycle-by-cycle simulation of eg. a turbine disc is far …

The fatigue test between 10 5—109 cycles of GH4169 nickel‑based superalloy commonly
used in aircraft engines is carried out by ultrasonic fatigue machine at 650℃. The S‑N curve …

Crack length evaluations for cyclic loading and sustained loading at high temperature and a
mix of both have been conducted on Inconel 718 surface crack specimens at 550∘ C. The …
