| Abstract Scope |
Modern fabrication methods (e.g. additive manufacturing) in concert with an elevated understanding of traditional bonding and processing methods (e.g. diffusion bonding) offer tantalizing flexibility in the design and realization of bimetallic joints. However, the complicated mechanical response produced by the similarly complicated and potentially defect loaded microstructures generated by these fabrication methods is exacerbated under dynamic loading, particularly in substantially mismatched bimetals. Here we look at the effect of defects and irregular dissimilar interfaces on the dynamic mechanical response of bimetallic joints—particularly the local deformation and damage behavior at these interfaces under shock compression and high-rate tension in couples such as diffusion bonded and explosively welded Aluminum-Titanium and cold-spray deposited Copper on an Aluminum substrate. These experiments as presented do not systematically interrogate processing variation but illustrate some of the issues introduced by the dynamic loading of the nonideal bimetallic interfaces achievable by realistic novel fabrication methods. |
