Abstract

This paper reports a study of multilayer nanolamellar Mo/Nb/TiNi composites designed by the principle of martensitic transformation enabled lattice strain matching. The composite was fabricated by hot packaged accumulative roll bonding (PARB) and wire drawing. The composite showed an apparent yield strength of ~1200 MPa and a recoverable superelastic strain of ~7%, with a mechanical damping of ~62 MJ/m³. Both the Nb and Mo nanolamellae sandwiched between the TiNi layers exhibit large elastic lattice strains of ~2.5% and ~3.0% respectively, benefited from the lattice strain matching and load transfer enabled by the martensitic transformation of the TiNi matrix. The Nb and Mo nanolamellae in the composite exhibited high component stresses of 2.4 GPa and 9.5 GPa, and each carries ~31% of the applied load even though with only 4% and 18% volume fractions, respectively.
