Abstract Scope |
The dynamic mechanical behavior of multiphase metal composites comprising dissimilar immiscible phases can be controlled through selection of constituents, processing routes and phase topologies. Here, we experimentally and computationally investigate a co-continuous tungsten-copper composite that is of interest because both constituents exist in significant fractions and exhibit highly dissimilar properties (CTE, density, yield stress, elastic modulus, crystal structure). First, quasi-static and dynamic loading experiments study how the strengths and rate sensitivities of the constituent phases manifest in the bulk composite’s response. Second, CT reconstructions of the composites are used to characterize phase connectivity for development of representative finite element models. These models can be extended to study a broad range of compositions to gain general insights into composites with co-continuous phase distributions. |
