Unit of processing, treatment and behavior of materials at high temperature
The unit satisfies the needs stemming from the optimization of the hot forming process of materials and from their upgrading under harsh conditions. The most outstanding abilities of the units are: Thermomechanical processing of steels and other metallic materials after the definition of the forming schedule as a function of the chemical composition and the features of the production line to eliminate the defects and to control the microstructure. Optimization of the final mechanical properties. Heat treatments. Material and process models (commercial and home developed). Interaction among materials: diffusion bonding, welding, dissimilar materials. In-service behavior: creep, oxidation, thermomechanical fatigue, degradation and failure mechanisms. Development and set-up of “ad-hoc” tests.
