The microstructure and phase transformations in the AlN-Al2O3 pseudo-binary
system of samples having an AIN content in mol% ranging between 44 and abo
ut 0 are reported as a function of the thermal treatments. The nature of th
e phase equilibria, temperature and composition range and coherence degree
of the different phases were studied by using various complementary experim
ental techniques. (C) 2000 Elsevier Science Ltd. All rights reserved.
