Understanding the Role of Fabrication Method on Metal Alloys Used in Nuclear Power Plants
07 Aug 2017 | | Contributor(s):: Esteban Bautista, Alexander Bullens, Janelle P Wharry
Current nuclear reactor components consist of forged or casted Iron-based or Nickel-based alloys. Both these fabrication techniques present challenges in long-term performance and structural integrity. A possible alternative investigated in this research includes Powder Metallurgy (PM)...
Multiscale Modelling of Nanoparticle Suspensions
12 Jun 2017 | | Contributor(s):: Pietro Asinari
In the present work a multiscale modelling approach is implemented to relate the nanoscale phenomena to the macroscopic bulk properties of nano-suspensions. Specifically, Molecular Dynamics (MD) simulations and Brownian Dynamics (BD) are synergistically integrated to understand the mechanisms...
