| Abstract Scope |
The potential to produce fully fused, metal components comprising multiple materials is widely recognized as one of the great untapped benefits that Directed Energy Deposition Additive Manufacturing may offer. The ability to vary alloy content within prescribed regions of a single, solid component promises potential to produce components that have locally tailored properties, for example: high strength bulk properties with locally enhanced corrosion protection; or continually varying coefficient of thermal expansion to reduce interfacial stress during temperature excursions. However, process parameters may need to be adjusted to ensure a robust deposition throughout the graded deposition, and alloy content may need to be controlled to minimize formation of undesirable phases that can lead to cracking. This presentation will discuss recent projects at Penn State’s CIMP-3D that have explored these issues in a variety of alloy systems. |
