从历年专利申请量、主要申请人、技术生命周期、主要申请国以及专利技术输入输出等方面着手，对国内以及世界其他国家钒铝合金技术的专利申请状况进行了统计分析，总体而言，该领域的专利在国内外的分布均没有显现集中趋势，未见战略性布局。此外，以该领域核心专利技术内容为基础，梳理了钒铝合金发展的主要技术脉络，并着重分析了钒铝合金产品在航空领域的发展情况，希望能为国内相关企业及科研机构提供参考。
The state of application for world patents about vanadium-aluminium alloy technique in recent years was re-viewed , which included patent application quantities , main applicants , technology life cycle , patent input and output situations and so on .Overall, the distribution of vanadium-aluminium alloy patents did not show central tendency both in the domestic and overseas .What’s more, with the purpose of providing a reference for the relative enterprises and scientific research institution in China , the history of vanadium-aluminium alloy technology was integrated based on the core patented technology , and the development of vanadium-aluminium alloy products used in the area of aviation was also analyzed .
