Thermo-Calc 2019b was released in June 2019 and introduces a new module for steel and slag processing, the Process Metallurgy Module, three new databases, a completely rewritten part of the calculation engine and more.Continue reading
Thermo-Calc Software recently published a new comprehensive tutorial which teaches about the role of diffusion in materials and how the Diffusion module (DICTRA) can be applied to materials design and processing, called The Role of Diffusion in Materials.
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.
