3D atomistic imaging of polymer nanocomposites with Atom Probe Tomography: experimental methodology, preliminary results and future outlook
James O. Douglas, Reza Salehiyan, Aparna Saksena +5
The use of polymer nanocomposites as gas barrier materials has seen increasing interest, including applications involving hydrogen transport and storage. Better understanding of ga…
Testing Outlier Detection Algorithms for Identifying Early-Stage Solute Clusters in Atom Probe Tomography
R S. Stroud, A. Al-Saffar, M. Carter +3
Atom probe tomography is commonly used to study solute clustering and precipitation in materials. However, standard techniques, such as the density based spatial clustering applica…
Atom probe analysis of BaTiO3 enabled by metallic shielding
Se-Ho Kim, Kihyun Shin, Xuyang Zhou +6
Atom probe tomography has been raising in prominence as a microscopy and microanalysis technique to gain sub-nanoscale information from technologically-relevant materials. However,…
Effect of alloying on the microstructure, phase stability, hardness and partitioning behavior of a new dual-superlattice nickel-based superalloy
C. Rodenkirchen, A. K. Ackerman, P. M. Mignanelli +10
A novel y-y'-y" dual-superlattice superalloy, with promising mechanical properties up to elevated temperatures was recently reported. The present work employs state of the art chem…
The effect of manganese and silicon additions on the corrosion resistance of a polycrystalline nickel-based superalloy
E. Anzini, N. Glaenzer, P. M. Mignanelli +3
The service lives of nickel superalloys are often limited by environmental degradation. The present study compares oxidation, sulfidation and hot corrosion at 750C of three variant…
Effect of bed temperature on solute segregation and mechanical properties in Ti-6Al-4V produced by selective laser melting
S. Pedrazzini, M. E. Pek, A. K. Ackerman +11
Advanced characterisation techniques were used on LPBF Ti-6Al-4V samples produced on a heated base plate. When the substrate temperature is 100°C the elongation is 6\%, which incre…
On the effect of Ti on Oxidation Behaviour of a Polycrystalline Nickel-based Superalloy
S. Pedrazzini, B. S. Rowlands, A. Turk +6
Titanium is commonly added to nickel superalloys but has a well-documented detrimental effect on oxidation resistance. The present work constitutes the first atomistic-scale quanti…
Radiation Damage and Thermal Recovery of Perovskite Superconductor Yttrium Barium Copper Oxide
A. Khobnya, M. E. Pek, G. Greaves +7
High temperature superconducting materials are being considered to generate the magnetic fields required for the confinement of plasma in fusion reactors. The present study aims to…
High Strain Rate Behaviour of Nano-quasicrystalline Al93Fe3Cr2Ti2 Alloy and Composites
S. Pedrazzini, M. Galano, F. Audebert +4
In the present work, we demonstrate for the first time the outstanding dynamic mechanical properties of nano-quasicrystalline Al93Fe3Cr2Ti2 at.% alloy and composites. Unlike most c…
