The True Mechanical Response of Copper Covetic Materials from Local Microtensile Tests
Abstract
Many unsubstantiated claims have been made about recently-patented copper-carbon “covetic” materials from Third Millennium Materials. However, based on available evidence, synthesis is variable; carbon entrainment is variable; and microstructures are variable. Therefore, any macroscale samples tested are likely to exhibit some composite mechanical response of both covetic and non-covetic local material regions. Since it is desirable to document and understand the “true” covetic response, we propose to develop or refine techniques to identify covetic regions, characterize local covetic properties, and propose mechanisms controlling the mechanics, deformation, and failure of covetic materials.
