Influence of chemical disorder on energy dissipation and defect evolution in concentrated solid solution alloys.

摘要: A grand challenge in materials research is to understand complex electronic correlation and non-equilibrium atomic interactions, how such intrinsic properties dynamic processes affect energy transfer defect evolution irradiated materials. Here we report that chemical disorder, with an increasing number of principal elements and/or altered concentrations specific elements, single-phase concentrated solid solution alloys can lead substantial reduction electron mean free path orders magnitude decrease electrical thermal conductivity. The subsequently slow dissipation affects dynamics at the early stages, consequentially may result less deleterious defects. Suppressed damage accumulation disorder from pure nickel binary more quaternary solutions observed. Understanding controlling by altering alloy complexity pave way for new design principles radiation-tolerant structural applications.
