Joining Dissimilar Materials for Harsh Environments

June 14, 2016

To reliably service harsh environments, functional assemblies often depend upon a set of properties selected from more than one material. Excluding fasteners, assemblies fashioned of dissimilar materials are typically formed utilizing high temperature processes such as diffusion bonding, brazing and welding. The challenge of designing such products are multifaceted and require consideration not only of [...]
