Abstract Scope |
For the past few decades our team at Ohio State has developed several techniques for accelerating metal to very high speeds, commonly 500m/s to over 1km/s, usually for impact welding. When performed with sequential thin flat pucks, this can be a method for additive manufacturing. In many respects this is like building up bodies with cold spray, except the typical sizes are orders of magnitude larger and acceleration is usually driven by a rapid plasma expansion from optical or electrical energy. This method can be very energy efficient, allow graded compositions and preserve complex microstructures in the flyer metal. Preliminary results, process attributes as well as a long-term vision will be provided in this presentation. |
