合金化元素对Nb-Si基超高温合金微观组织和性能的影响
Effect of Alloying Elements on Microstructures and Properties of Nb-Si Based Ultra-high Temperature Alloys
摘要
Abstract
The alloying effects of Ti,B,Al and Cr on the microstmctures and properties of Nb-Si based alloys are often published,while there are less research about Zr,Mo,W and Hf.The addition of these elements not only can optimize the microstmctures of Nb-Si based alloys,but also can improve the overall performances,so analyzing and summarizing the alloying effects of Zr,Mo,W and Hf have great significance for the design and application of Nb-Si alloys.Accordingly,the alloying effects of Zr,Mo,W and Hf on the microstructures,mechanical properties and high temperature oxidation resistance were focused in this paper.关键词
