Archy Warhol - June 2017


To obtain 3D architectured composites, a Ti-6Al-4V structure is manufactured using additive manufacturing (Electron Beam Melting), then the matrix is sintered around the structure using Spark Plasma Sintering. The Ti-6Al-4V / Cu composite showed here has been obtained by this process. Dense interfaces and diffusion profiles can be obtained by this process as illustrated on this pop-SEM back-scattered electrons image (x2K).
Widmanstätten patterns can be observed in the Ti-6Al-4V metal (up left and right) and large area of diffusion around interface and grain boundaries can be distinguished in the copper.
But one can see more here: an explostion, a magma... "The more you look at the same exact thing, the more the meaning goes away, and the better and emptier you feel" A. Warhol.
