Advanced Engineering Materials, EarlyView.A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys
Advanced Engineering Materials, EarlyView.This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Distance Matrix Completion by Numerical Optimization [PDF]
, 1997 Consider the problem of determining whether or not a partial dissimilarity matrix can be completed to a Euclidean distance matrix. The dimension of the distance matrix may be restricted and the known dissimilarities may be permitted to vary subject to ...

On Some Distance Spectral Characteristics of Trees
AxiomsGraham and Pollack in 1971 presented applications of eigenvalues of the distance matrix in addressing problems in data communication systems. Spectral graph theory employs tools from linear algebra to retrieve the properties of a graph from the spectrum ...

On the uniqueness of Euclidean distance matrix completions
Linear Algebra and its Applications, 2003 An \(n\times n\) real matrix \(D=(d_{ij})\) is called a Euclidean distance matrix iff there exist points \(x^1,x^2,\ldots ,x^n\) in some Euclidean space such that \(d_{ij}=\| x^i-x^j\| ^2\) for all \(i,j=1,2,\ldots ,n.\) An \(n\times n\) real matrix \(A=(a_{ij})\) is called symmetric partial matrix if only some of its entries are specified and if \(a_ ...

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing
Advanced Engineering Materials, EarlyView.This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...
