As a part of PNNL Physical and computational sciences directorate seed LDRD project, we aim to develop a predictive understanding of the phase transformation pathway and defect evolution mechanisms…

Correlative In-situ/Ex-situ Approaches to Reveal the Mass Transport Mechanisms During Shear Deformation

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Bharat Gwalani

Solid phase processing (SPP) of alloys using multi-scale shear-deformation produces not only enhanced mechanical properties, but also results in nanoscale metastable phases. Revealing mass transport…

Andrew Felmy

Project type

Large-Scale EMSL Research

We propose a comprehensive experimental and theoretical investigation of the role of interfacial water and CO2 on the energies, mechanisms, and rates of reactivity of a series of orthosilicate and…

Thermally Stability of Nanostructures - An Experimental and Modeling Investigation

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Aashish Rohatgi

The goal of this proposal is to develop nanostructured alloys that can be fabricated in bulk form (>1 cm3) without compromising their nanostructure, either during the fabrication process or during…

NANOSCALE COMPOSITIONAL ANALYSIS OF HEAVY-METAL RICH BIO-MATERIALS

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Arun Devaraj

The jaws, leg claws, stings and other “tools” of a large fraction of arthropods, some worms and mem-bers of other phyla, contain extraordinary amounts of heavy metals or bromine (e.g. Zn, Mn, Fe, Cu,…

High Resolution Studies to Reveal Coupled Effects of Stress and Hydrogen on Stress Corrosion Cracking of Steels

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Arun Devaraj

Hydrogen exhibits complex behaviors in materials because of its ability to donate all its electrons or to double their number, depending on the environment. The rich variety of H-induced processes is…
