| Abstract Scope |
A process map is an explicit representation of the microstructural response of a material to imposed process parameters. Historically, creating these maps has required a large design of experiments (DOE) to characterize the flow performance and microstructure from uniaxial compression experiments conducted at six or more strain rates and temperatures to various incremental total strain accumulation. In 2000, Jackson et al. (DOI: 10.1179/026708300101507433) introduced the double-cone geometry. This novel geometry reduced the volume of material necessary for the DOE by imposing a linearly increasing effective strain over the radius. We adopt this approach to establish microstructurally-informed process models in 316 stainless steel in the presented work. We discuss modification of the geometry for material constraints of additively manufactured preforms and sheet/plate material; the quantification of microstructural metrics; and first attempts at computationally efficient models that would enable on-line modification of robotic incremental rolling and forming operations. |
