Production of Flexible Transparent Conducting Films of Self-Fused Nanowires via ...
Launching silver nanowire suspension water out of a supersonic nozzle at a specific speed allows creating a transparent thin film mat on a surface, that fuses/evaporates on impact. The resulting thin film is transparent, conductive, and stretchable.

High-strength bulk nano-crystalline silver prepared by selective leaching combined with spark plasma sintering
They seem to be up to steel strength now, but volume production is iffy. Military want thi for EFP slug plate as it's cheaper than tantalum but better than copper.

3D printing tungsten » The Unwanted Blog
Interesting comment about using 3D printing to create specialty engineered alloys, specifically silver impregnated tungsten for better heat conductivity internally to avoid localized melting on tungsten rocket nozzle throats. In this application, it wouldn't be a conventional casted alloy, nor would it be a gradient mixed/poured alloy either, but perhaps a design specific 3D spacial gradient? Or would you be doing the design equivalent of embedding a heat pipe of sorts in the tungsten for short range directed heat transfer?
