Determination of gamma-gamma' lattice misfit in a single-crystal nickel-based superalloy using convergent beam electron diffraction aided by finite element calculations Micron, 43(2-3):396-406 2012 ISSN: 0968-4328 DOI: 10.1016/j.micron.2011.10.009 Resume: In single-crystal nickel-based superalloys, the lattice mismatch associated with interface coherency between gamma matrix and gamma' precipitates has a strong influence on mechanical properties. The unconstrained lattice misfit in a single-crystal of the MC2 nickel-based superalloy is determined using convergent beam electron diffraction measurements and finite element calculations. The apparent lattice parameters of both constrained phases are obtained in thin foils, using a new multi-pattern approach, which allows for unambiguous determination of all the lattice parameters considering the real symmetry of the strained crystals. Finite element calculations are used to establish relations between the constrained and unconstrained lattice parameters, with the stress relaxation resulting from the thin foil geometry taken into account.

•	Appolaire, Benoit, Perevoshchikova, Nataliya, Teixeira, Julien and Denis, Sabine A convex hull algorithm for minimization of Gibbs energy in two-phase multicomponent alloys Solid State Phenomena, 172-174(Part 1):1214-1219 2011 ISSN: 1012-0394 DOI: 10.4028/www.scientific.net/SSP.172-174.1214 Resume: We have adapted the Quickhull algorithm with the general dimension Beneath-Beyond algorithm [6] for computing the convex hull of the Gibbs energy hypersurface of multicomponent two-phase alloys. We illustrate the salient features of our method with calculations of isothermal ferrite-austenite equilibria in Fe-C-Cr. Finally, successive equilibrium calculations in a Fe-C-Cr-Mo steel over a large temperature range show the benefit of computing the convex hull before performing the conventional Newton-Raphson search.

•	Appolaire, Benoit, Aeby-Gautier, Elisabeth, Teixeira, Julien Da Costa, Dehmas, Moukrane and Denis, Sabine Non-coherent interfaces in diffuse interface models Philisophical magazine, 90(1-4):461-483 2010 ISSN: 1478-6435 DOI: 10.1080/14786430903334324 Resume: We propose a description of incoherent and semi-coherent interfaces within the framework of diffuse interface modelling: accounting for the discontinuity of tangential displacements is an issue addressed by introducing a new field, called the incoherency field, located in the diffuse interface and able to release the shear stresses tangential to the interface. After having demonstrated the ability of the model to recover trends obtained by sharp interface models of sliding interfaces, the process of loss of coherency is investigated by assuming a local process which would result from the competition between the shear stress release at the interface and the interfacial energy increase.
