Abstract Scope |
The strength of metallurgically bonded planar interfaces between additively manufactured (AM) GRCop-84 – Inconel 625 bimetals is investigated. The baseline dynamic tensile (spall) behavior of the monolithic parent materials is determined by plate-on-plate impact experiments employing multiple PDV probes. Bimetallic samples with either normal or inclined interfaces show a diverse range of responses between and within each experiment, due to differences in wave propagation characteristics. The responses include failure along a single uniform or irregular interface plane, or in three distinct material regions. The resulting values of the spall and interface failure strengths are distinctly different and correspond to those of the Inconel 625, GRCop-84, and the interface. The results provide a unique method for probing the dynamic failure strength of bimetal interfaces and spall strength of the respective metals in the same experiment. |
