Researchers from Professor Jian Chen's group at Southeast University  have provided a new multi-scale impact testing case study carried out using a NanoTest instrument supplied by Micro Materials Ltd.   The School of Materials Science and Engineering at Southeast University in Nanjing, China conducts research in diverse areas of materials science, including advanced metallic materials. 

The study describes multi-scale impact tests performed on a CoCrNi-based medium entropy alloy and how, by combining multi-scale impact and structural characterisation, new insights into the size-related mechanism of high-strain-rate deformation were revealed.

The knowledge gained will ultimately assist  the researchers in designing impact-resistant materials needed for extreme impact applications, such as those experienced when jet engine turbine blades undergo collisions with solid particles.
