Title: Mechanical Properties of Uranium Silicides by Nanoindentation and Finite Elements Modeling

Abstract

Three methods were used to measure the mechanical properties of U3Si, U3Si2, and USi. Quasi-static and continuous stiffness measurement nanoindentation were used to determine hardness and Young's modulus, and microindentation was used to evaluate the bulk hardness. Hardness and Young's modulus of the three U-Si compounds were both observed to increase with Si content. Finally, finite elements modelling was used to validate the nanoindentation data calculated for U3Si2 and estimate its yield strength.
