This study focuses on a non-invasive characterization of a set of ancient kris by means of neutron imaging and diffraction methods. The kris (or keris) is an elongated dagger or short sword distinctive of Malaysia and Indonesia. Its complex structure results from the combination of several layers of iron, steel and sometimes iron-nickel alloy welded together in an intricate pattern that is brought out on the polished surface of the blade through the use of an etchant. Based on the tomographic analysis, four different structural arrangements were identified for the first time. Complementarily, the average quality of the ferrous materials used to produce the four kris was evaluated via time-of-flight neutron diffraction analysis. New details about the manufacturing process of a still little studied class of artefacts were derived from our investigation.
