| 中文摘要 | In the present paper, the microstructure, compressive properties at different temperatures and hardness of NiAl-Cr(Mo)/Nb alloy prepared by injection-casting were investigated. Compared with the conventionally cast alloy, the injection-cast alloy exhibited a fine microstructure, i.e. the fine eutectic cell and interlamellar spacing as well as fine primary NiAl phase and Laves phase Cr(2)Nb due to the high cooling rate. In addition, the area fraction of primary NiAl phase at the cell interior or cell boundaries and eutectic cell increased. The compressive ductility and yield strength at room temperature increased by about 100% and 50% over those of conventionally cast alloy, respectively. However, both alloys possessed the similar high temperature strength. The Vickers hardness of injection-cast alloy also increased markedly. (C) 2008 Elsevier Ltd. All rights reserved. |
