Multiscale Process Modeling of Bulk Nanolaminates

National Laboratory: 
Los Alamos National Laboratory
Computational Tools Class: 
Materials Processing
Processing/Manufacturing Class: 
Fabrication and synthesis
Description: 

Computational models at Los Alamos National Laboratory can help guide the design of processing pathways for making stable bulk nanolaminate microstructures with tailored properties. The current model capability delivers microstructure-property relationships that evolve within the material during deformation processing. LANL also uniquely offers process-aware synthesis of bulk nanolaminates with target microstructures.

Capability Bounds: 

Presently, computational modeling at LANL can be applied to thermomechanical deformation within temperatures less than 0.5 Tm and strain rates less than 106/s.

Unique Aspects: 

LANL institutional investments have developed and validated this unique capability for materials of interest to the nuclear energy sector.

Availability: 

A computer cluster for parallel processing is preferred.
