aThe reaction may take place in a very limited area and conse-quently products formation. By this route, the formation of Si will be definitely lower than the eutectic point of Al-Si phase diagram (13 wt.%), thus excluding any precipitation of solid Si and pore clogging at the infiltrati...
CALPHAD(CALculation of PHAse Diagram)技术是目前非常成熟且用途极为广泛的相图评估和计算方法,它不仅是材料动力学,显微组织演变计算模拟的热力学平台,而且能够广泛地应用于新材料的设计与研制.Cu,Fe,Nb,Ni,Si,Cr,Ti等是Al基合金中的主要合金元素或添加元素.为了设计铝基合金成分,优化制备工艺,并有效地提高合金性能...
Binary Systems The Al-Nd phase diagram [ 2005Gao ] shows the following compounds: Nd 3 Al ( D 0 19 , Ni 3 Sn-type hexagonal), Nd 2 Al ( C 23, Co 2 Si-type orthorhombic), NdAl (ErAl-type orthorhombic), NdAl 2 ( C 15, MgCu 2 -type cubic), αNdAl 3 (Ni 3 Sn-type ...

The phase equilibria between (body centred cubic, bcc), ± (hexagonal closed packed, hcp), Ti3 Al±2 (hcp), and Ti5 Si3 (hcp) in the TiAlSi system have been investigated in the temperature range 7001200°C. Isothermal sections of the ternary phase diagram have been assessed employing ...
Binary Systems The Al-Er phase diagram [Massalski2, 2009Puk ] depicts the following intermediate phases: ErAl 3 ( L 1 2 , AuCu 3 -type cubic), ErAl 2 ( C 15, MgCu 2 -type cubic), ErAl (ErAl-type orthorhombic), Er 3 Al 2 (Zr 3 Al 2 -type tetragonal), and Er 2 Al ( C...
Al-Si-TiB2 composites, having Al-13.5Si alloy compositions, close to the eutectic point on hyper-side of the Al-Si phase diagram are shown in Figs. 4a–c. Nearly globular shaped fine dendrites of the α-Al phase are seen in the microstructure of B1 (Fig. 4a) along with rod like Si...
