| Abstract Scope |
In this talk, we present an Integrated Computational Materials Engineering (ICME) framework for the rapid development and exploitation of process-structure-property-performance (PSPP) chains in Additively Manufactured NiTi-based Shape Memory Alloys (SMAs). We start by describing a novel approach for the rapid determination of the optimal printable region in AM NiTi-x based SMAs using a combination of fast-acting thermal models and suitable CALPHAD models for the thermo-physical properties of SMAs. Once the printable region has been identified, a novel approach to predict the rate of Ni differential evaporation is used to establish predictive relations connecting process conditions to transformation temperatures. Models capable of predicting the evolution of second-phase precipitates under arbitrary thermal histories are also included in the framework. It is shown how such a sophisticated PSPP model chain could potentially be used in the inverse design of 4D-printed SMA-based components. |
