Strain burst speeds in metallic glass micropillars

Effect of composition and thermal history on deformation behavior and cluster connections in model bulk metallic glasses

“…A smaller stress drop indicates relatively more stable deformation process 57 , in agreement with the observed homogeneous deformation behavior of Pt 42.5 Pd 0 in nano-indentation experiments. In previous studies, brittle-natured Mg- and Au-based BMG micropillars exhibited smaller numbers of strain bursts during micro-compression in contrast to numerous strain bursts for ductile Zr-based BMG micropillars 58 . Individual serration events correspond to the accumulation and release of elastic energy in order to bypass the energy barrier for shear band formation 59 .…”

A study of the deformation and failure mechanisms of protective intermetallic coatings on AZ91 Mg alloys using microcantilever bending

“…8(d). The dislocations stacks are considered to have been caused by the localised shearing induced by the compressive stress generated at the bottom of the cantilever during bending [24,25]. Although significant plastic deformation occurred in both phases on either side of the interface, the two phases remain fully bonded, with no visible delamination at the interface.…”
