摘要：

Results on investigations of structure and phase transformations of fine-grained h-BN graphite-like powders induced by heating to concentrated light beam of different energies in nitrogen flow in optical furnace are given. It is presented structures obtained on the surface of heated samples of moulding h-BN powders and on titanium substrate. Surface of titanium substrate has been studied by scanning electron microscopy to reveal the new structures and new morphologies produced after exposure to different light energies. Complicated structure of whiskers formed on the surface of heated samples of pressed h-BN powders has been investigated by transmission electron microscopy. A pronounced evolution in structure on the surface of heated samples of moulding h-BN powders is demonstrated. (C) 2007 Elsevier B.V. All rights reserved.
