nil-ductility transition temperature, nil ductility temperature, nil-ductility temperature, NDT, NDT temperature, NDTT
the temperature at which fracture initiates with essentially no prior plastic deformation (see: ductile-to-brittle transition temperature), temperatuur, mille juues metalli purunemisele ei eelne plastseid deformatsioone; st metalli murdepinna makrostrukuur on iseloomulik haprale purunemisele (vt plastne-habras siirdetemperatuur/külmahapruslävi)
