Deformation twins as a probe for tribologically induced stress states
Friction and wear of metals are critically influenced by the microstructures
of the bodies constituting the tribological contact. Understanding the
microstructural evolution taking place over the lifetime of a tribological
system therefore is crucial for strategically designing tribological systems
with tailored friction and wear properties. Here, we focus on
single-crystalline CoCrFeMnNi that is prone to form twins at room temperature.
Deformation twins feature a pronounced orientation dependence with a
tension-compression anisotropy, a distinct strain release in an extended volume
and robust onset stresses. This makes deformation twinning an ideal probe to
experimentally investigate the complex stress fields occurring in a
tribological contact. Our results clearly show a grain orientation dependence
of twinning under tribological load. Unexpectedly, neither the crystal
direction parallel to the sliding nor the normal direction are solely decisive
for twinning. This experimental approach is ideal to experimentally validate
tribological stress field models, as is demonstrates here
The Influence of Digitalization on Emergent Processes of Entrepreneurial Ecosystems - a Complexity Science Perspective
Recent literature conceptualizes digitalization as an important enabler of entrepreneurial activity. However, the understanding of how digitalization influences the broader entrepreneurial landscape remains limited. In this context, there have been appro
