  "abstract": "Although hammering was a widespread way of shaping copper alloys in several past societies, the mechanical metallurgy and hammering techniques for copper-based alloys have not yet been fully documented. This study aims to propose a new methodology based on a multiscale analysis of hammering indicators. Copper test plates have been subjected to varying degrees of strain hardening using a testing device that simulates ancient hammering conditions. After a topographic study of the impacts, the microstructure of cross-sectioned samples was characterised using EBSD and correlated with mechanical properties via microhardness measurements. The experimental data were cross-referenced with a finite-element numerical simulation to model the mechanical hammering test and to provide a local description of the plastic deformation. The results identified an index of plastic strain from the grain orientation spread (GOS), suitable for comparing the distribution of plastic deformation between samples. The methodology was applied to a replica of an Angkorian vase. The study highlights that coupling microstructural characterisation via EBSD with numerical simulation is a useful complement to conventional metallographic studies. This approach is a first step toward providing new insights into copper-based alloy manufacturing techniques in the future.",
