Abstract
It is demonstrated experimentally that an irradiation-induced transformation of planar as well as curved graphite to diamond can be carried out without applying pressure. A specimen containing both graphite and diamond is irradiated at high temperature with an electron beam in an electron microscope. It is observed that the diamond crystals grow on the expense of graphite, although graphite is, at the low pressure prevailing here, the stable phase of carbon.Keywords
