Presentation Title Three-Dimensional, Location-Specific Prediction of Phase Transformations in Aerospace Alloys With Transient Temperature Fields
Author(s) Evan Adcock, Brodan Richter, Joshua Pribe, George Weber
On-Site Speaker (Planned) Evan Adcock
Abstract Scope Predicting phase transformations is an important aspect of integrated computational materials engineering as it enables relating the material processing to the final phase fraction and resulting properties during techniques such as powder bed fusion (PBF) additive manufacturing. Phase prediction models have been developed for various alloys and processes but frequently lack transferability due to being custom designed for specific processes and material systems. This presentation exhibits an easily modifiable Python-based phase transformation modeling approach using Johnson–Mehl–Avrami–Kolmogorov (JMAK) kinetic equations that is integrated within NASA Langley Research Center’s ‘Materialite’ framework. This approach was developed to simulate location-specific phase transformations in transient temperature fields. A model for alpha/beta morphology development in PBF Ti-6Al-4V and a model for phase evolution and precipitate formation during post-process aging of PBF Alloy 718 will be presented. The presented phase transformation simulation capabilities are anticipated to support processing and post-processing optimizations of PBF alloys.
