Deformation twinning plays a crucial role in the strong anisotropic strength, poor
deformability, and texture and microstructure evolutions of hexagonal metals. Modifying …

The mechanical performance and multi-step TRIP/TWIP behaviors in a metastable Fe 55 Mn
25 Co 10 Cr 10 were systematically investigated at room temperature (RT) and 77 K. The …

Asymmetric tilt boundaries on conventional twin boundaries (TBs) are significant for
understanding the role of twins on coordinating plastic deformation in many metallic alloys …

Mechanical behavior of alloys is influenced by segregation of solute atoms, which affects
deformation mechanisms, such as slip and twinning. In this study, we report on an atomic …

Compared to the disordered HCP metals, the α 2-Ti 3 Al phase is reluctant to twin due to its
D0 19 ordered structure. Recently, abundant {20 2¯ 1} compression twins were observed in …

One-fourth of the global energy losses are spent to overcome friction, making it particularly
important to reduce and minimize friction between contacting materials. Hexagonal close …

We present a systematic investigation of {10 1¯ 2} extension twinning mechanism in single
crystal magnesium micropillars deformed over seven orders of magnitude of strain rate, from …

Twin nucleation in high symmetry cubic structures is closely related to the activities of
dissociated lattice dislocations. However, in low symmetry hexagonal close-packed (HCP) …

Length scale dependent microstructural heterogeneities serve as effective pathways in
engineering materials for providing simultaneous strength-ductility enhancement. In this …

The present study focuses on the roles of structure, stress and temperature on the mobility of
facets bounding twin domains and on the overall impact on the growth kinetics of {10 1¯ 2} …
