D1.1 COOPHS Comprehensive overview of the project

The present document provides a comprehensive overview of project COOPHS.

This description includes a detailed review of the state of the art related to recycling of high performance steel grades, and how it can affect boron steel grades and press hardened products. It also includes a description of the current knowledge on detailed characterization of segregations and precipitation of tramp elements, using specific techniques based on TEM (Transmission Electron Microscopy) or APT (Atom Probe Tomography). Finally, aspects related to the evaluation of fracture toughness are discussed, together with the implications of Hydrogen Embrittlement.

The review of the state of the art is used to formulate the main challenges and gaps in knowledge found in the literature, and discuss how the project is expected to address these gaps and bring additional value.
