Coexistence of multi-deformation modes in beta Ti alloys with improved yielding strength and ductility [PDF]

MATEC Web of Conferences, 2020
By suppressing SIM (stress induced martensitic) phase transformations, a strong and ductile beta TWIP (twinning induced plasticity) Ti-Mo based alloy was achieved, thanking to the coexistence of mechanical twinning ({112} mode and {332} mode) and ...

Twinning in Hexagonal Close-Packed Materials: The Role of Phase Transformation

Metals, 2023
Twinning is a major mechanism of plastic deformation in hexagonal close-packed (hcp) structures. However, a mechanistic understanding of twin nucleation and growth has yet to be established.

Triple and double twin interfaces in magnesium—the role of disconnections and facets

Scientific Reports, 2023
Twin boundaries have been shown to deviate from the twinning planes in hcp metals, and facets have often been observed in twin interfaces. This study presents a twinning disconnection-based model for faceting in single, double and triple twin boundaries ...

EQUILIBRIUM CONDITION OF RESIDUAL EDGE WEDGE-TYPE NANOTWIN IN POST-DEFORMED SOLID BODY

Наука и техника, 2017
An equilibrium condition of residual edge wedge-type nanotwin in a deformed solid body has been derived in the paper. The condition conclusion is based on the necessity to ensure an equilibrium of force balance acting on every twinning dislocation from ...
