Abstract Scope |
As manufacturing technologies advance, parallel innovations in material design must be accomplished to produce more advanced structural components. It is clear that in order to fully realize the benefits of additive manufacturing (AM), new feedstocks that are conducive to AM must be developed. Transformation induced plasticity (TRIP) and twinning induced plasticity (TWIP) steel alloys are attractive for structural applications due to exceptionally high work hardening rates and high toughness, but these alloys have largely been investigated in wrought form. There is a need to develop wire feedstocks to enable high deposition rate wire arc additive manufacturing of TRIP and TWIP steels. In this presentation, we describe the development and manufacturing of high manganese TRIP and TWIP wire feedstocks, along with microstructures and tensile properties of the WAAM builds. The challenges and opportunities of using powder-core wire for developing novel feedstocks for structural applications will be discussed. |
