Francisca G. Caballero, Research Professor at the Spanish National Centre for Metallurgical Research (CENIM-CSIC) and NewAIMS partner, participated in the MS&T24 Technical Meeting and Exhibition, held from October 6th to 9th in Pittsburgh, Pennsylvania, United States.

During the MS&T24 event, Francisca G. Caballero delivered a presentation titled “Phase Transformations in Additive Manufacturing of Tool Steels,” which provided an overview of the NewAIMS project and the previous research outcomes that inspired it. Her talk was part of the “Iron and Steel (Ferrous Alloys)” conference topic and was included in the session “Austenite Formation and Decomposition V: A Symposium in Memory of Prof. Mats Hillert,” chaired by Amy Clarke from Los Alamos National Lab.

The presentation focused on the complexity of non-equilibrium and non-uniform microstructures formed during the Laser Powder Bed Fusion (LPBF) process in maraging steels, exploring the precipitation of intermetallic phases and the growth or reversion of austenite during the ageing process. Additionally, it covered strategies to enhance the thermal stabilization of austenite in the microstructure through preheating and post-heat-treatment, using specially designed tool steels for LPBF manufacturing.

The Materials Science & Technology (MS&T) technical meeting and exhibition series, organised by the American Ceramic Society, the Association for Iron & Steel Technology (AIST), and The Minerals, Metals & Materials Society (TMS), is a long-standing, recognised forum for fostering technical innovation at the intersection of materials science, engineering, and application. The MS&T provides attendees with the chance to learn from industry-leading experts, showcase their own research to top professionals, and foster meaningful cross-disciplinary collaborations.
