Embrittlement of Materials

Part of the The International Cryogenics Monograph Series book series (ICMS)


In general, materials tend to increase in strength as their temperature is lowered. The deformation of metals occurs with the movement of crystal-lattice dislocations. As the temperature is raised, the thermal energy of the vibrating atoms assists this movement. Hence, as the temperature is lowered, the decreased thermal vibration of the metal lattice adds to the strength of the material.1 However, in the design of cryogenic equipment it is usually best to use the ambient-temperature strength because of temperature gradients that might exist within the equipment and also because cryogenic equipment frequently must operate at warmer temperatures.
