Ductile B2 Intermetallics-Driven Strength-Ductility Synergy in Heterolaminated Multi-Principal Element Alloys. [PDF]
Adv Sci (Weinh)Intrinsic phase toughening transforms a brittle B2 intermetallic into a plastically deformable, load‐bearing phase, while a heterogeneous laminated architecture suppresses strain localization and interface cracking. The synergy between ductile intermetallics and mesoscale heterogeneity establishes a general design strategy for breaking the long ...

Advances in ultrafine-grained materials
Materials Today, 2013 This review addresses new developments in the processing and properties of ultrafine-grained (UFG) materials. These materials are produced through the application of severe plastic deformation to conventional coarse-grained metals and typically they have grain sizes within the submicrometer or even the nanometer range.

Deformation-softening in ultrafine-grained materials
IOP Conference Series: Materials Science and Engineering, 2020 Abstract Plastic deformation is conventionally considered as a route for strengthening of metallic materials. During plastic straining, different crystal defects, such as dislocations, stacking faults and grain boundaries form, hardening the material. On the other hand, plastic deformation may also cause unexpected softening in ultrafine-

Potential of ultrafine grained materials as high performance penetrator materials
EPJ Web of Conferences, 2012 The shear formability and the metal jet formability are important for the kinetic energy penetrator and the chemical energy penetrator, respectively. The shear formability of ultrafine grained (UFG) steel was examined, mainly focusing on the effects of ...
