WebYes crystalline carbon by itself is brittle. Any force applied along one of the axes of the crystal lattice can cause it to shear. However, small strands of carbon can be made immensely strong - when they're made, pains are taken to ensure the carbon atoms bond together parallel to the long axis of the strand, giving it great tensile strength. Embrittlement is a series complex mechanism that is not completely understood. The mechanisms can be driven by temperature, stresses, grain boundaries, or material composition. However, by studying the embrittlement process, preventative measures can be put in place to mitigate the effects. There are several ways to study the mechanisms.
