Effect of Heavy Ion Irradiation Dosage on the Hardness of SA508-IV Reactor Pressure Vessel Steel

open access: yesMetals, 2017
Specimens of the SA508-IV reactor pressure vessel (RPV) steel, containing 3.26 wt. % Ni and just 0.041 wt. % Cu, were irradiated at 290 °C to different displacement per atom (dpa) with 3.5 MeV Fe ions (Fe2+).

Depth-Sensing Indentation Creep Behavior of Nanostructured Thermal Barrier Coatings from As-Synthesized t’-8YSZ Feedstocks

open access: yesNanomaterials, 2019
Nano-indentation is a popular method to characterize the micromechanical properties of nanostructured 8YSZ coatings. However, little research has focused on the creep behavior of nano-indentation and only the elastic modulus and nanohardness have been ...

Nano‐indentation investigation on nano‐twinned Cu–Ag alloys with GBAZ segregation

open access: yesMicro & Nano Letters, 2022
For the sake of comprehending the mechanical mechanisms of nano‐twinned (NT) Cu–Ag alloys with grain boundary affect zone (GBAZ) segregation, molecular dynamics (MD) simulations were used to observe its behaviours during the nano‐indentation progress ...

Analysis of residual stress around a Berkovich nano-indentation by micro-Raman spectroscopy

open access: yesAIP Advances, 2019
Nano-indentation is a destructive measurement that introduces non-uniform residual stress around each nano-indentation. Herein, the residual stress distribution around a Berkovich nano-indentation on (001)- and (111)-plane silicon was studied by micro ...

LOCAL NANO-MECHANICAL PROPERTIES OF CROSS-LINKED POLYBUTYLENE

open access: yesActa Polytechnica CTU Proceedings, 2020
Cross-linking is a process in which polymer chains are associated through chemical bonds. The cross-linking level can be adjusted by the irradiation dosage and often by means of a cross-linking booster. The polymer additional cross-linking influences the
