Structure of complex oxide nanoparticles in a Fe-14Cr-2W-0.3Ti-0.3Y(2)O(3) ODS RAF steel

Nadine Baluc

One of the most crucial steps in the development of oxide dispersion strengthened (ODS) reduced activation ferritic (RAF) steels is the engineering of their microstructure, which includes control of the type and size of oxide nanoparticles. In this work, t ...

3D Phase-Field Simulation of Micropore Formation during Solidification: Morphological Analysis

Michel Rappaz, Alain Jacot, Hossein Meidani

A 3D multiphase-field (PhF) model has been developed in order to study the formation of a micropore constrained to grow in a solid network (i.e., pinching effect). The model accounts for the pressure difference due to capillarity between liquid and gas, th ...
