具有O相結(jié)構(gòu)的Ti2AlNb合金是在Ti3Al系合金基礎(chǔ)上拓展出來的新型金屬間化合物材料，兼具了高的高溫強(qiáng)度和相對較低的密度的特點(diǎn)，有望替代現(xiàn)有的Inconel 718鎳基高溫合金，用于制造高推重比航空發(fā)動(dòng)機(jī)中的非轉(zhuǎn)動(dòng)部件甚至轉(zhuǎn)動(dòng)部件。概述了Ti2AlNb合金的特點(diǎn)和近年來我國在Ti2AlNb合金工程化研究方面取得的主要進(jìn)展，對Ti2AlNb合金存在的不足以及當(dāng)前研制過程中存在的主要問題進(jìn)行了闡述，指出應(yīng)立足于現(xiàn)有的鈦合金冶煉和加工裝備，并結(jié)合Ti2AlNb合金自身的特點(diǎn)，開發(fā)出成本更低、生產(chǎn)效率更高的工業(yè)化生產(chǎn)工藝技術(shù)。
- 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.
