Deciphering the role of dispersoids in dispersion-strengthened tungsten alloys on the mechanical properties and irradiation- driven response under nuclear fusion reactor-relevant conditions
… time for recovery, as a high number of tungsten-dispersoid interfaces is presented to pin grain boundaries and enhance mechanical properties. However, deuterium irradiation results in surface blistering, while the dispersoid composition and distribution in the bulk samples has been shown to …

Friction stir welding of high temperature alloys
… A critical finding was 'strain induced dispersoid agglomeration'. For Ti-6Al-4V alloy, transformed ß microstructure formed composed of fine acicular α phase (~500 nm in thickness). The fine grain structure facilitated globularization during tensile deformation at 625 ºC.</p> …

Origins of Embrittlement of an Al-Zn-Mg-Cu Alloy Post Additive Friction Stir Deposition
… state. Critical to this process is the role of dispersoid particles, which are modified by shear processes which provide high energy spots for thermally stable precipitate nucleation. Removal of these dispersoid particles by an alloy modification had been shown to eliminate the embrittlement …

Additive Friction Stir Deposition of Aerospace Al-Zn-Mg-Cu-Zr Alloys: Leveraging Processing and Metallurgical Science for Structural Repair
… as well as the influence of the zirconium dispersoid particle on quench sensitivity when applied to thicker sections. It was found that AA7050 after AFSD has significantly more quench sensitivity than traditionally processed material and through STEM, it was determined that this was due to …

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 …
