Abstract
Various embodiments relate to additive manufacturing in which the Langmuir equation can be used to predict composition in the processing. This equation can be integrated into a model with knowledge of elemental solubility and relative reactivity of relevant elements in the additive manufacturing processing. Use of thermodynamic principles can be programmed into a finite element modeling strategy integrating the Langmuir equation, coupling the thermal fields of additive manufacturing and the surrounding environments with the rules and/or equations to predict solute pickup and/or solute loss. The modeling strategy can be implemented to identify the elements in relative concentrations to be used in the additive manufacturing processing to provide for the controlled loss of certain elements to prevent absorption of unwanted elements into molten material, formed by additive manufacturing, from the atmosphere around the molten material. Additional systems and methods are disclosed.
