摘要	Predominantly single-phase Hf-2[Al(Si)(4)]C-5 ceramic hits been fabricated by an Ill Situ reaction/hot-pressing method using Al. Si and graphite its starting materials Hf-2[Al(Si)](4)C-5 Shows comparable mechanical properties to Zr-2[Al(Si)](4)C-5, and lower hardness and stiffness but higher strength and toughness than HfC The stiffness decreases slowly with temperature and at 1600 degrees C it remains 83% of that at ambient temperature Compared to Zr-2[Al(Si)](4)C-5 and HfC, however, Hf-2[Al(Si)(4)C-5 exhibits it relatively higher coefficient of thermal expansion,. all intermediate specific heat capacity and it lower thermal conductivity (C) 2009 Acta Materialia Inc Published by Elsevier Ltd.
