Phase Transformation-Induced Interfacial Debonding of Silica Inclusions in Iron
Andreas Mortensen, David Hernandez Escobar, Julie Nathalie S Gheysen, Alejandra Inés Slagter
We document that in unstressed, undeformed, samples of pure iron containing silica inclusions precipitated by melt deoxidation, the iron matrix and a small fraction of the silica inclusions are locally separated at room temperature by a void. Thermal cycli ...
New York2023Crystalline or amorphous? A critical evaluation of phenomenological phase selection rules
In this work, we reviewed the available phase selection rules comprising atomic size and topological aspects, entropies, enthalpies, melting points, valence and itinerant electron concentrations, as well as electronegativity, and validated them using a car ...
ELSEVIER SCI LTD2023Phase and microstructure selection in peritectic alloys under high G-V ratio
Wilfried Kurz, Stéphane Dobler
A new model for the case of a superposition of a phase transformation and a microstructure transition from columnar plane front to equiaxed dendritic growth for peritectic alloys is presented. This model is applied to Fe-Ni alloys where a phase transition ...
WALTER DE GRUYTER GMBH2022Characterization of untransformed ferrite in 10Cr and 12Cr ODS steels
Two new ferrito-martensitic oxide dispersion strengthened (ODS) steels reinforced with (Y, Ti, O) nanoparticles were elaborated using a high-energy attritor. The milled powder was consolidated by hot extrusion at 1050 degrees C. The two types of ODS steels ...
ELSEVIER SCI LTD2021Microstructural Evolution Study of Fe-Mn-Al-C Steels Through Variable Thermomechanical Treatments
Roland Logé, Oscar Zambrano Zambrano
The microstructural evolution of the two austenitic alloys Fe-20Mn-3Al-0.7C wt pct and Fe-20Mn-6Al-0.7C wt pct when different thermal and thermomechanical treatments are performed has been studied. To this end, a generic industrial die of 100 ton capacity ...
SPRINGER2021APT/TEM characterization of the element segregation in ferritic/martensitic steels after irradiation in SINQ
Ferritic /martensitic (FM) steels are among the most important materials in various nuclear applications. As radiation-induced segregation (RIS) is one of the major factors for embrittlement of nuclear materials, thereofre it is essential to study the RIS ...
EPFL2021Processing and micro-mechanical characterization of multi-component transition MC carbides in iron
Andreas Mortensen, Goran Zagar, Léa Deillon, Marta Fornabaio, Lionel Michelet
We prepare multi-component transition monocarbides of chosen composition by arc-melting together a pre-alloy of the transition metals and cast iron. Based on the elements Ti, Ta, V, Nb and W, 51 different binary, ternary and quaternary compositions are pro ...
