摘要
随着钛合金在我国航空、航天、兵器、海洋和化工等领域用量和应用范围的不断扩大,对钛合金高综合力学性能、低成本和加工工艺性能提出了更加苛刻的要求。通过基于组织参数设计的合金化、细晶强化、相变强化和强韧化工艺控制等综合强韧化技术,研制出具有高强韧、抗疲劳、耐损伤、抗冲击等综合性能良好匹配的新型高性能钛合金,是扩大钛合金在高端领域的用量与应用水平,实现产业升级转型,满足下一代应用需求的重要保障。
With the continuous extension of the application quantity and range for titanium alloy in the fields of national aviation,space,weaponry,marine and chemical industry,etc.,even more critical requirements to the comprehensive mechanical properties,low cost and process technological properties of titanium alloy have been raised.Through the alloying based on the microstructure parameters design,and the comprehensive strengthening and toughening technologies of fine grain strengthening,phase transformation and process control of high toughening,the new type of high performance titanium alloy which has good comprehensive properties of high strength and toughness,anti-fatigue,failure resistance and anti-impact has been researched and manufactured.The new titanium alloy has extended the application quantity and application level in the high end field,realized the industrial upgrading and reforming,and met the application requirements of next generation equipment.
