摘要：
The Al-rich part of the Al-Ru phase diagram was reinvestigated by scanning and transmission electron microscopy, powder X-ray diffraction and differential thermal analysis. The Al(6)Ru, Al(13)Ru(4), Al(5)Ru(2), Al(2)Ru, Al(3)Ru(2) and AlRu phases were confirmed. The Al(6)Ru is formed peritectically at 734 degreesC, Al(13)Ru(4) peritectically at 1420 degreesC and Al2Ru peritectically at 1805 degreesC. An orthorhombic Al(5)Ru(2) phase (a = 0.78, h = 0.66 and c = 0.42 nm) isostructural to Al(5)Fe(2) was found to be formed at 1492 degreesC by a peritectic reaction of Al(2)Ru with the liquid and to decompose at 1340 degreesC to Al(2)Ru and Al(13)Ru(4). The Al(3)Ru(2) phase is formed by a peritectoid reaction from Al(2)Ru and AlRu at 1675 degreesC. (C) 2003 Elsevier Science Ltd. All rights reserved.
