摘要:
具有O相结构的Ti2AlNb合金是在Ti3Al系合金基础上拓展出来的新型金属间化合物材料，兼具了高的高温强度和相对较低的密度的特点，有望替代现有的Inconel 718镍基高温合金，用于制造高推重比航空发动机中的非转动部件甚至转动部件。概述了Ti2AlNb合金的特点和近年来我国在Ti2AlNb合金工程化研究方面取得的主要进展，对Ti2AlNb合金存在的不足以及当前研制过程中存在的主要问题进行了阐述，指出应立足于现有的钛合金冶炼和加工装备，并结合Ti2AlNb合金自身的特点，开发出成本更低、生产效率更高的工业化生产工艺技术。
Abstract:
Ti2AlNb alloy with orthorhombic phase represents the youngest class of alloys emerging out of Ti-Al titanium aluminides, as a constituent in Ti3Al-based alloy. With excellent high temperature performance and lower density, this new material is aimed to replace the existing Inconel 718 nickel-based superalloy, used in the manufacture of high thrust weight ratio aeroengine non-rotating parts or even rotating parts. This article briefly summarized the characteristics of Ti2AlNb alloy and the main progress made in the engineering technologies of Ti2AlNb alloy in China in recent years. In addition, the existing shortcomings of Ti2AlNb alloy and the main problems in the current research were also discussed. It was pointed out that the industrial production process technology with lower cost and higher production efficiency should be developed basing on the existing titanium alloy smelting and processing equipment and combining with the characteristics of Ti2AlNb alloy.
