Molecular Dynamics Simulations of Compression-Tension Asymmetry in Plasticity of Fe Nanopillars
Con Healy, Graeme Ackland
Tension-compression asymmetry is a notable feature of plasticity in bcc single crystals. Recent experiments reveal striking differences in the plasticity of bcc nanopillars for ten…
Shear Melting and High Temperature Embrittlement: Theory and Application to Machining Titanium
Graeme J Ackland, Con Healy, Sascha Koch +2
We show that alloying with rare earth metals (REMs) can dramatically improve the machineability of a range of titanium alloys, even though the REM is not incorporated in the alloy…
Shear melting and high temperature embrittlement: theory and application to machining titanium
Con Healy, Sascha Koch, Carsten Siemers +2
We describe a dynamical phase transition occurring within a shear band at high temperature and under extremely high shear rates. With increasing temperature, dislocation deformatio…
MD Simulations of Compression of Nanoscale Iron Pillars
Con J. Healy, Graeme J. Ackland
It is now possible to create perfect crystal nanowires of many metals. The deformation of such objects requires a good understanding of the processes involved in plasticity at the…
