| Abstract Scope |
Hot cracking is a major problem associated with additive manufacturing (AM) of many steels. In order to understand hot cracking susceptibility specific to materials and processing for materials design, it is critical to accurately predict the nonequilibrium kinetics of solidification and solid-solid phase transformations during AM. In this presentation we demonstrate how Scheil and DICTRA simulations and Thermo-Calc Property Models can be applied to predict the nonequilibrium microstructure during AM in some tool steels and stainless steels. Microstructure-specific materials properties, for example thermal expansion, can be obtained with the support of necessary databases. The capabilities and limitations of the computational tools are discussed, and directions of development are suggested. |
