Nanoscale Multilayer Metallic Composites
Investigating Deformation and Failure Mechanisms in Nanoscale Multilayer Metallic Composites

Objectives: Uncover fatigue damage suppression and ultimate failure mechanisms of NMM composites. Develop a novel fatigue experiment for NMM composites. Establish guidelines for designing NMM with optimum properties.

Uniqueness and Innovation: Design a trimetallic NMM composite (Cu/Ni/Nb) which might possess more superior properties than the two types of bimetallic systems(Cu/Ni & Cu/Nb). This might be achieved by building a new system that combines the two bimetallic systems with their respective interface strengthening mechanisms and properties.
