Researchers at Ohio University conducted a FIERF-funded inquiry to understand what cold deformation did to additive-manufactured (AM) shapes. This understanding is critical to harnessing the advantages of both processes and improving the mechanical properties of AM parts as AM technologies continue to emerge and mature.
In order to achieve the benefits that grain flow can impart to a forged component, there is a need to understand the end service of the component to produce a forging with the grain flow of the required orientation in the critical region(s) of the component.
The focus in the first three parts of this series was on the basics of grain flow and their effects on mechanical properties. In this fourth installment, the typical grain flow for various manufacturing processes will be reviewed.
