Deformation, recovery and recrystallization of TiAl.

Deformation and Recrystallization Behaviors in Magnesium Alloys

Dynamic Recovery and Recrystallization During Hot-Working in an Advanced TiAl Alloy Dynamische Erholung und Rekristallisation während der Warmverformung in einer TiAl-Hochleistungslegierung

Intermetallic TiAl alloys are light-weight high-temperature materials and intended to partly replace Ni based alloys in jet engines. Due to difficult forming operations, component prices are high and limit the possible field of application. During hotworking, recovery and recrystallization effects determine the microstructural evolution and thereby the mechanical properties of the finished part...

Dynamic Recrystallization under Hot Deformation of a PH Stainless Steel

Dynamic recrystallization, DRX, behaviour of a precipitation hardened, PH, stainless steel was studied in connection with microstructural developments in a compression test. The experimental results showed that the dominant mechanism of softening is DRX, but at high strain rates and low temperatures, ie, high Zener-Holman parameter, Z, work hardening and dynamic recovery, DRV, produced a pancke...

Characterization and influence of deformation microstructure heterogeneity on recrystallization

The microstructure resulting from plastic deformation of metals typically contains heterogeneity on several length scales. This is also true for samples deformed to large strains, where an important form of heterogeneity is in the variation in microstructural refinement by high angle boundaries. A methodology for quantifying this type of heterogeneity based on the identification of areas classi...

Deformation Behavior of Al0.25CoCrFeNi High-Entropy Alloy after Recrystallization

Cold rolling with subsequent annealing can be used to produce the recrystallized structure in high entropy alloys (HEAs). The Al0.25CoCrFeNi HEAs rolled to different final thickness (230, 400, 540, 800, 1000, 1500 μm) are prepared to investigate their microstructure evolutions and mechanical behaviors after annealing. Only the single face-centered cubic phase was obtained after cold rolling and...
