In this paper, investigation of the softening behaviour of a supersaturated Al-Mn-Fe-Si alloy during annealing after cold rolling has been carried out. Two different homogenization conditions were considered, of which one gives a condition of a large amoun ...
This article describes the microstructure and Charpy impact properties of an Fe-14Cr-2W-0.3-Ti-0.3Y(2)O(3) oxide dispersion strengthened (ODS)-reduced activation ferritic (RAF) steel, manufactured either from elemental powders or from an Fe-14Cr-2W-0.3Ti p ...
Microstructures, and especially grain boundary populations, are characterized in a γ/γ′ nickel-base superalloy submitted to various thermomechanical treatments involving hot deformation and subsequent supersolvus annealing. The resulting microstructures co ...
Under certain circumstances abnormal grain growth occurs in Nickel base superalloys during thermomechanical forming. Second phase particles are involved in the phenomenon, since they obviously do not hinder the motion of some boundaries, but the key parame ...
The aim of the thesis is to obtain more understanding about the influence of plastic deformation on the microstructural changes observed in single crystal (SX) Ni-based superalloys using diffraction techniques. This work was organised around two main probl ...
Microstructure evolution has been studied in the nickel-based superalloy PER®72 subjected to hot torsion, to annealing below the primary γ' solvus temperature and to annealing at a supersolvus temperature, with a special emphasis on grain size and twin con ...
A phenomenological modelling approach has been developed for the description of die massive and lamellar microstructures which form in gamma-TiAl alloys at high and moderate cooling rates, respectively. The nucleation of both massive and lamellar gamma is ...

According to various studies, Grain Boundary Engineering (GBE) is likely to enhance mechanical properties of polycrystalline materials. The present investigation highlights some relationships between thermomechanical process (TMP) parameters of a commercia ...
Copper and copper alloys typically experience a sharp loss in ductility at intermediate temperature, induced by grain boundary damage and fracture processes. The susceptibility of the material to intermediate temperature embrittlement is, as a result, stro ...
Mechanisms responsible for the embrittlement of leaded "free-machining" copper alloys at intermediate temperatures (i.e. around 400 °C) are examined using a combination of microstructural and mechanical characterization. Tensile tests are conducted on pure ...
