Hong Jin Kim,A. Emge,R. E. Winter,P. T. Keightley,Woo Kyun Kim,Michael L. Falk,David A. Rigney +6 more
TL;DR: In this article, an explosively driven tribotester was used to test aluminum and steel sliding surfaces with high velocity and high pressure within a very short time, and the sliding surfaces showed material transfer, severe plastic deformation of the softer material, evidence of high strain and strain rate, and nanostructure formation at the surface and subsurface.
