The role of interfacial structure in the evolution of precipitate morphology
Three aspects of precipitate growth by a ledge mechanism in a Ni-45wt%Cr alloy were investigated. The strain energy for ledge formation and ledge growth kinetics and the emission of structural defects were studied experimentally during the growth of bcc laths from an fcc matrix. The elastic strain …

Mechanical Properties and Microstructure of Copper Alloys and Copper Alloy-Stainless Steel Laminates for Fusion Reactor High Heat Flux Applications
… regions including: microporosity, new precipitate formation, existing precipitate morphology changes and interdiffusion of constituent elements.

Formation of uniform particles: Morphology and colloidal stability, and stable particle growth during precipitation from titanium alkoxides
… size distribution. Factors that control particle morphology in the absence and presence of shear and the mechanisms of growth of colloidally stable suspensions are discussed. Two factors are identified which control colloidal stability and precipitate morphology during precipitation: interaction …

Characterization and Mechanical Properties of Nanoscale Precipitates in Modified Al-Si-Cu Alloys Using Transmission Electron Microscopy and 3D Atom Probe Tomography.
… the 319 type alloys arise due to small size of precipitate and complex aging response caused by multi components. It is important to determine the chemical composition, crystal structure, and orientation relationship as well as precipitate morphology in order to understand the precipitation …

Interfacial structure of delta phase in Inconel 718 and the selection of precipitate habit planes
… between a γ (fcc) matrix and plate-shaped precipitates of the δ (orthorhombic) phase in Inconel 718. Based upon transmission electron microscopy (TEM) observations, the average habit plane was confirmed to be (111)<sub>γ</sub> which is consistent with previous reports. A parallel array of …

On the plastic deformation behaviour of nickel-based superalloys: low cycle fatigue and stress orientation effects
… slip line spacings and shear step lengths at the precipitate interfaces are measured for the first time ever with a new methodology, allowing for quantitative comparisons. Non-coplanar stacking faults are observed to be the main obstacles against which dislocations in a slip band pile up and …

The role of defects during precipitate growth in a Ni-45wt% Cr alloy
… between an fcc matrix and a lath-shaped bcc precipitate in Ni-45 wt% Cr were investigated. The interfacial structure on the side facet of the precipitate consists of regular structural ledges and misfit dislocations. No regular defect structure can be found on the habit plane, or broad face, …
