A team from CNPEM Deputy Directorate of Technology, comprising Rafael Defavari, Thais Alonso, Daniel Salomão Doretto, Fernanda Regina Francisco, Daniel Kakizaki, Pedro Martins, Patricia Branco, and Maysa Terada, has won the prestigious Gleebe Award 2024. This award, which recognizes excellence and innovation in physical metallurgy and materials science, was presented during the Brazilian Congress of Materials Engineering and Science (CBCiMat 2024), held from November 24 to 28 in Fortaleza, Brazil.
The winning project, Optimization of Parameters for Diffusion Bonding in Cu C110 Alloys Using the Gleeble 3800, explores methods for manufacturing cryogenic components essential to advanced technologies operating at extremely low temperatures (<123 K). The research focuses on joining copper sheets, chosen for their high thermal conductivity and flexibility, which are crucial for reducing vibrations and ensuring stability in sensitive systems.
The study highlights the use of the Gleeble 3800 thermomechanical simulator to identify optimal diffusion bonding conditions, achieving more homogeneous and efficient joints. These improvements enhance the thermal and electrical performance of components, contributing to the development of more reliable and optimized cryogenic systems for high-tech applications.
The award underscores the trajectory of excellence of CNPEM’s Deputy Technology Directorate, which has amassed expertise in areas such as cryogenics, materials engineering, and manufacturing since the development of the UVX and Sirius projects.
