duktilbrittletransitioksi
Duktilbrittletransitioksi, often abbreviated as DBTT, refers to a temperature below which a material that is typically ductile exhibits brittle behavior. Ductility is the ability of a material to deform plastically under tensile stress before fracturing, while brittleness is characterized by fracture with little or no plastic deformation. This transition is a critical property for many materials, particularly metals and polymers, as it dictates their performance and reliability under various service conditions.
The DBTT is not a sharp point but rather a range of temperatures over which the material's
Understanding and controlling the DBTT is crucial in material selection and design, especially for applications exposed
