What Does NDTT Stand For?

NDTT stands for Nil Ductility Transition Temperature

NDTT, or Nil Ductility Transition Temperature, refers to the specific temperature at which a material, typically a metal, transitions from a ductile state to a brittle state. Below this temperature, the material exhibits significantly reduced plasticity and increased susceptibility to fracture under stress. Understanding NDTT is crucial in materials science and engineering, particularly for applications involving low-temperature environments, where maintaining structural integrity is essential.
