Multiscale Process Modeling of Bulk Nanolaminates

National Laboratories:Los Alamos
Computational Tools:Materials Processing
Processing/Manufacturing:Fabrication & Synthesis

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.
