Eco-friendly Alloys Designed for Additive Manufacturing

Laser Additive Manufacturing (LAM) is promoted as an eco-friendly process with very low waste. However, the yield in the powder manufacturing process is only as little as 30% for powder based LAM, thus it is critical to develop low impact feedstocks. This proposal will yield critical insights that are necessary to guide the development of LAM suitable metallic alloys that can obtained from recycled materials. Here, we propose to take advantage of ID11’s unique capability to map the 3D distribution of crystallographic phases and measure 3D stress states at high spatial resolution. This will be applied to a crystalline multi-phase grain network to generate microscale detail from prototype alloys. Specifically, data will enable failure prevention strategies based on impurities concentrations in the recycled materials.
