Track 1: Advanced Heat Treatments and Alloy Design for Metal Additive Manufacturing

Organizers

Abstract of the track

Metal Additive Manufacturing (AM) enables the production of complex three-dimensional metal components directly from digital models. However, the intrinsic characteristics of AM processes—such as rapid solidification, cyclic thermal histories, and steep thermal gradients—often lead to heterogeneous microstructures and high levels of residual stress. To achieve mechanical and functional properties comparable to or superior to those of conventionally manufactured components, post-processing heat treatments are frequently required. Nevertheless, heat treatments developed for traditional manufacturing routes are often unsuitable for AM materials, making the design of optimized, AM-specific thermal post-processing strategies a critical and time-consuming challenge. In parallel, significant research efforts are focusing on the development of novel alloys specifically tailored for AM that minimize or eliminate the need for post-processing heat treatments. This track aims to gather recent advances in innovative heat treatment strategies for AM alloys, providing a critical discussion of their effects on microstructural evolution, thermophysical properties, and mechanical performance. In addition, contributions addressing the design and stability of new heat-treatment-free or heat-treatment-light alloys, particularly for high-temperature applications, are strongly encouraged.
