Abstract
The influence of microstructure on the mechanical properties of materials has been the focus of research over several decades, with various attempts made to characterize this size effect numerically, e.g. the Hall-Petch relationship. This behaviour is overlaid with an extrinsic size dependence that scales with the testing technique used, whereby the smaller the sampled volume the stronger the material appears to behave. Considering the growing trend towards miniaturised mechanical testing, particularly in the electronics industry and nuclear community, both forms of the size effect need to be fully understood in order to achieve engineering-relevant results. In particular, knowing how the two contribute cumulatively in different material systems is non-trivial and requires further investigation.
