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