Applications of Thermo-Calc to Additive Manufacturing of Metals

A few pieces of 3D printed metal components.Additive manufacturing of metals is transforming materials design and processing in ways unimaginable even 10 years ago, offering the freedom to produce complex parts without the restraints of traditional manufacturing. 

However, Additive Manufacturing is a complex process and the mechanical properties of these materials and the parameters which control their reproducibility are not yet well understood. For example, additive processes are typically associated with rapid cooling rates and large thermal gradients. This can give rise to high levels of residual stress in the final part and local inhomogeneities in alloy composition during solidification. Also, the effect of multiple thermal cycles on material properties is sometimes unknown and typically does not result in the properties of a similar cast or wrought metal.

A lot of research is now being published in this area by members of our community using Thermo-Calc and we want to share some of this work with you. Below you will find a sampling of some of the work that is being done using Thermo-Calc and our add-on modules for diffusion and precipitation to research additive manufacturing of metals.

DICTRA used to model changes to Ni-based superalloy during Interdiffusion

In a  paper published in the January 2016 issue of Journal of Phase Equilibria and Diffusion , Vol. 37 No. 2 2016, the homogenization model within DICTRA together with the TCNI and MOBNI databases were used to model the interdiffusion processes in the Ni-based superalloy CMSX-10 and was shown to have good agreement with experimental values.

TC-Toolbox for MATLAB® with Thermo-Calc Used to Optimise a Nickel-based Superalloy

In a 2015 issue of Metallurgical and Materials Transactions A a group at Michigan University, Department of Materials Science & Engineering used TC-Toolbox for MATLAB® in conjunction with Thermo-Calc to optimise a nickel-based alloy, resulting in a lower cost alloy with 25% improvement in properties when assessed with their utility function.
