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. In conclusion, finite elements modelling was used to validate the nanoindentation data calculated for U₃Si₂ and estimate its yield strength.

Extending the range of constant strain rate nanoindentation testing

Journal Article Merle, Benoit ; Higgins, Wesley H. ; Pharr, George M. - Journal of Materials Research

Constant strain rate nanoindentation hardness measurements at high sustained strain rates cannot be made in conventional nanoindentation testing systems using the commonly employed continuous stiffness measurement technique (CSM) because of the “plasticity error” recently reported by Merle et al. [Acta Mater.134, 167 (2017)]. To circumvent this problem, here we explore an alternative testing and analysis procedure based on quasi-static loading and an independent knowledge of the Young's modulus, which is easily obtained by standard nanoindentation testing. In theory, the method applies to any indentation strain rate, but in practice, an upper limit on the rate arises from hardware limitations inmore »« less

Nano-scale mechanical behavior of uranium silicide compounds

Conference Carvajal-Nunez, U. ; Institute for Materials Science and the Center for Integrated Nanotechnologies - CINT, Los Alamos National Laboratory, Los Alamos, NM, 87545 ; White, J. T. ; ...

Uranium silicide compounds exhibit a range of attractive material properties for nuclear fuel applications, but little is known regarding their mechanical behavior. The structure of nuclear fuels at high burnup can prove to be especially difficult given the significant changes in both chemistry and microstructure caused by fission products. Nano-indentation appears to be a valuable addition to post irradiation examination. The present focus is assessment of the room temperature modulus and hardness of U{sub 3}Si{sub 2}, U{sub 3}Si{sub 5} and USi materials. Each of the compositions under investigation was synthesized via arc melting of the pure metals in an Armore »« less
First-Principles Investigation of Mechanical and Thermodynamic Properties of Nickel Silicides at Finite Temperature

Journal Article Wen, Zhiqin ; Zhao, Yuhong ; Hou, Hua ; ... - Physics of the Solid State

First-principles calculations are performed to investigate lattice parameters, elastic constants and 3D directional Young’s modulus E of nickel silicides (i.e., β-Ni{sub 3}Si, δ-Ni{sub 2}Si, θ-Ni{sub 2}Si, ε-NiSi, and θ-Ni{sub 2}Si), and thermodynamic properties, such as the Debye temperature, heat capacity, volumetric thermal expansion coefficient, at finite temperature are also explored in combination with the quasi-harmonic Debye model. The calculated results are in a good agreement with available experimental and theoretical values. The five compounds demonstrate elastic anisotropy. The dependence on the direction of stiffness is the greatest for δ-Ni{sub 2}Si and θ-Ni{sub 2}Si, when the stress is applied, while thatmore »« less

Finite-element modeling of nanoindentation for determining the mechanical properties of implanted layers and thin films

Conference Knapp, J A ; Follstaedt, D M ; Barbour, J C ; ...

The mechanical properties of implanted layers and thin films on dissimilar substrates are difficult to accurately determine. Nanoindentation of the layer provides information, but detailed numerical modeling is required in order to separate the properties of the layer from those of the substrate. We describe here the procedures we have developed to accomplish this modeling with the commercially available finite-element code ABAQUS. Using these techniques, we are able to extract from nanoindentation testing the yield stress, Young`s modulus, and hardness of the layer material, with an absolute accuracy of at least 20%. The procedure is applicable to layers as thinmore »« less

Microstructure and nanoindentation of the rostrum of Curculio longinasus Chittenden, 1927 (Coleoptera: Curculionidae)

Journal Article Singh, Sudhanshu S. ; Current address: Department of Materials Science and Engineering, Indian Institute of Technology Kanpur, Uttar Pradesh 208016 ; Jansen, Michael A. ; ... - Materials Characterization

The rostrum is an extension of the cuticle of the head of weevils (Coleoptera: Curculionidae) and is often used to bore holes for oviposition (the process of laying eggs) into host plant tissue where larval development occurs. In members of the genus Curculio Linnaeus, 1758, the rostrum is long, slender, and strongly curved, but is nevertheless used to excavate straight bore-holes in the fruit of various host plants, through significant deformation of this structure. In this study, scanning electron microscopy (SEM) was used to examine the rostrum of Curculio longinasus Chittenden, 1927, leading to a microstructural model that describes itsmore »« less
