Auteur : Swedish Centre of Technical Terminology,Définition
Condition caused by embrittlement in connection with the precipitation of foreign phases in a material of given composition and given temperature. The word "blue brittleness" was previously limited to the decrease in toughness suffered by certain steels prone to ageing. The name reflects the surface colour typical of those steels during the tempering of which the condition was first discovered. The relationship between blue brittleness in a steel and its composition and heat treatment is not fully understood.
