we recently published a paper on measuring bulk properties of irradiated copper from nanoscale samples:
Hope you find this interesting!
The Interdisciplinary Centre for Advanced Materials Simulation (ICAMS) is a new research centre at the
RuhrUniversity Bochum, Germany. At ICAMS an interdisciplinary team of scientists from engineering,
materials science, chemistry, physics and mathematics is working on the development and application
of a new generation of simulation tools for multiscale materials modelling.
It is well known thatdislocations in FCC metals are composed of partial dislocations separated bystacking faults. When consideringthe reactions of dislocations with each other, such as in DD simulations, it is necessary to determine therelative positions of the partials in order to correctly describe theconfigurations that are created in the reactions. Here we describe a geometric method for correctly determiningthe relative positions of the partials. The results we obtain can also be found by applying an axiom, or rule,given in the book by Hirth and Lothe. At the end of this tutorial we describe this axiom and apply it to someof the problems we have discussed. Our hope is that the geometric method we describe will give readers anintuitive sense of the geometry of partial dislocations and confidence in usingthe Hirth/Lothe axiom.
