Abstract Scope |
Combining computational thermodynamic modeling, numeric heat transfer simulation, and interface response function models allows for the potential control of microstructural features and resulting mechanical properties, especially when considering rapid, non-equilibrium solidification commonly encountered in additive manufacturing. When combined with mechanical testing and metallography, modeling and simulation results can be rationalized to real world results. As an example, the yield strength of aluminum silicon alloys can be controlled through manipulating the input of energy. This technique could allow yield strength to be uniquely varied throughout an additively manufactured part. Additionally, the technique could be used to optimize process parameters to yield desired microstructures while limiting potentially deleterious phases such as delta ferrite in additively manufactured steels. |
