| Abstract Scope |
Cold spray Additive has emerged as a key competitor for existing technologies such as casting, ingot metallurgy and powder metallurgy. It offers a combination lower cost manufacturing with enhanced properties and performance that’s particularly well-suited for manufacturing Titanium shaped intermediates and mill products directly. The property benefits arise from solid state deposition, which promotes microstructural refinement and eliminates macrosegregation. When used in conjunction with novel low-cost titanium metal powder production, Cold spray Additive becomes a transformational manufacturing technology challenging traditional Titanium manufacturing routes.
This presentation will describe CSIRO’s patented Cold spray technologies to manufacture continuous mill products such as Billets and Performs, all these directly from low cost Titanium binder-less powder feedstocks. The characterization of the microstructure and mechanical properties produced with different powder feedstocks will be described, together with results of holistic CFD model used to predict temperature, velocity, deposition efficiency and distribution of particles existing the jet. |
