致密Mo-Si-B合金制备的新方法

A New Method for Preparation of Compactness Mo-Si-B Alloy

对高温结构材料Mo-Si-B合金的研究越来越热。Mo-Si-B合金优异的抗氧化性,抗蠕变,断裂韧性,组织性能稳定和使用寿命长被认为是未来新一代的航空发动机结构材料和高温抗氧化涂层材料的发展方向。本文在研究当前国内外制备Mo-Si-B合金各种方法的基础上,提出了一种新的方法制备Mo-Si-B合金。结果表明,新方法制备的Mo-Si-B合金的致密性达99%以上。

Currently, there are more and more researches on Mo-Si-B alloy which is a kind of high temperature structural material. Mo-Si-B alloys are considered to be the next generation of aero-engine structural materials and the development direction of high temperature oxidation-resistant coating materials, because of their excellent oxidation resistance, creep resistance, fracture toughness, microstructure and properties stability and long life. Based on the various methods of making Mo-Si-B alloys at home and abroad, we put forward a new method for preparation of Mo-Si-B alloy. The results show that the density of Mo-Si-B alloys made in the new method is more than 99%.
