Formation of metastable phases of carbon during rapid cooling of graphite

A graphite-to-diamond transition has been observed experimentally during the rapid cooling of polycrystalline graphite that has been heated by means of an infrared laser. The results are explained both by a "freezing" of the structure and also by stresses that appear in a graphite single crystal upon rapid cooling.
