Ductile rupture in metals is a phenomenon that affects a wide range of applications from
forming of automotive body panels to failure of pressure vessels. The incipient stage …

Abstract Bulk nanostructured (ns)/ultrafine-grained (UFG) metallic materials possess very
high strength, making them attractive for high strength, lightweight and energy efficient …

Magnesium alloys have received considerable research interest due to their lightweight,
high specific strength and excellent castability. However, their plastic deformation is more …

The abrupt occurrence of twinning when Mg is deformed leads to a highly anisotropic
response, making it too unreliable for structural use and too unpredictable for observation …

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

The standard model is applied for partial disclination pairs in hard materials. These defects
comprise two partial disclinations and an intervening fault that can be a twin boundary, grain …

In this research, a high ductility Mg-Gd-Mn magnesium alloy was designed and developed,
with an elongation capability surpassing 50%. To gain insights into the underlying …

Dislocation slip and twinning are equally important in the plastic deformation of hexagonal
close packed crystals. Basal slip and extension 10 1¯ 2< 1¯ 011> twins can be activated …

A different type of defect, the coherency disclination, is added to disclination types.
Disconnections that include disclination content are considered. A criterion is suggested to …

In this work, pure Ti and Ti-5at.% Al alloy are both cold rolled, and then characterized to
observe deformation twins {10 1¯ 1}. Many two-layer steps are observed at the {10 1¯ 1} …
