Correlation between homogenisation parameters and property evolution of AA3104 CBS after hot finish rolling
… the growth of intermetallic particles (IMPs) and dispersoids, affecting mechanical performance and texture evolution in following rolling stages. This study investigates the impact of different homogenisation procedures on the microstructure and mechanical properties of AA3104 during lab-scale hot …

Deciphering the role of dispersoids in dispersion-strengthened tungsten alloys on the mechanical properties and irradiation- driven response under nuclear fusion reactor-relevant conditions
Tungsten is the material of choice for plasma-facing components in future plasma- burning fusion reactors because of its high melting point, high sputter threshold, and low hydrogenic species retention. However, tungsten is an intrinsically brittle material, displaying no room temperature ductility …

Directional Recrystallization of an Additively Manufactured Oxide Dispersion-Strengthened Nickel-Base Superalloy
… NiCoCr powders were decorated with oxide dispersoids using resonant acoustic mixing then consolidated with laser powder bed fusion. The as-printed ODS materials were fully dense with retained nanoscale Y2O3 dispersoids and a small grain size of order 10 μm. The as-printed materials were …

Microstructural evolution during the homogenization heat treatment of 6XXX and 7XXX aluminum alloys
… the extrusions, and precipitation of nano-sized dispersoids (for Cr-, Zr-, Mn-, Sc-containing alloys), which inhibit grain boundary motion to prevent recrystallization. Post-homogenization cooling reprecipitates some of the phases, changing the flow stress required for subsequent extrusion. These …

Creep resistance of directionally solidified eutectic ceramics : experiments and model
… circumvent the c-ZrO₂(Y₂0₃) domains acting as dispersoids, resulting in the stress exponents larger than 3. The mechanistic dislocation creep model is in very good agreement with the experiments. Low angel boundaries in the form of asymmetrical tilt boundaries are found between columnar …

Microstructure property development in friction stir welds of aluminim based alloys
… between the dislocations and the fine Al6(Fe,Mn) dispersoids, indicated that establishing a structure-property model requires the incorporation of the various strengthening factors. Stereological studies of the grain size and intermetallic particle distributions in the TMAZ indicated that the …
