What Does FATT Stand For?

FATT stands for Fracture Appearance Transition Temperature

FATT, or Fracture Appearance Transition Temperature, refers to the critical temperature at which a material transitions from a ductile to a brittle fracture mode. This parameter is essential in materials science and engineering, as it helps predict the fracture behavior of materials under various temperature conditions, influencing material selection and design in industries such as aerospace, automotive, and structural engineering. Understanding FATT allows engineers to ensure the reliability and safety of components subjected to different thermal environments.
