Local Stress States and Microstructural Damage Response Associated with Deformation Twins in Hexagonal Close Packed Metals
The current work implements a correlative microscopy method utilizing electron back scatter diffraction, focused ion beam and digital image correlation to accurately determine spatially resolved stress profiles in the vicinity of grain/twin boundaries and tensile deformation twin tips in commercially pure titanium. Measured local stress gradients were in good agreement with local misorientation...
متن کاملUniaxial stress-driven coupled grain boundary motion in hexagonal close-packed metals: A molecular dynamics study
Stress-driven grain boundary (GB) migration has been evident as a dominant mechanism accounting for plastic deformation in crystalline solids. Using molecular dynamics (MD) simulations on a Ti bicrystal model, we show that a uniaxial stress-driven coupling is associated with the recently observed 90 GB reorientation in shock simulations and nanopillar compression measurements. This is not consi...
متن کاملElectronic Origins of Anomalous Twin Boundary Energies in Hexagonal Close Packed Transition Metals.
Density-functional-theory calculations of twin-boundary energies in hexagonal close packed metals reveal anomalously low values for elemental Tc and Re, which can be lowered further by alloying with solutes that reduce the electron per atom ratio. The anomalous behavior is linked to atomic geometries in the interface similar to those observed in bulk tetrahedrally close packed phases. The resul...
متن کاملThe shock and spall response of three industrially important hexagonal close-packed metals: magnesium, titanium and zirconium.
Magnesium, titanium and zirconium and their alloys are extensively used in industrial and military applications where they would be subjected to extreme environments of high stress and strain-rate loading. Their hexagonal close-packed (HCP) crystal lattice structures present interesting challenges for optimizing their mechanical response under such loading conditions. In this paper, we review h...
متن کاملThe Strength of Binary Junctions in Hexagonal Close-Packed Crystals
A comparative study of non-coplanar binary dislocation junctions in magnesium (Mg) and beryllium (Be) is presented to examine the effects of elastic properties and active Burgers vectors on junction formation and destruction in hexagonal close-packed (hcp) crystals via discrete dislocation dynamics simulations. Two junction configurations formed at intersecting prismatic ð01 10Þ=basal ð0001Þ pl...
