摘要: 

αα + β两相钛合金是航空、航天关键工程领域的核心材料。提高钛合金锻件性能,特别是大型锻件的性能稳定性一直是工程领域的研究热点。钛合金锻件中普遍存在微织构,严重降低了锻件的疲劳等关键性能,是制约钛合金锻件综合性能的关键因素之一。通过优化热加工工艺提高材料晶体取向分布均匀性是进一步改善合金性能的可行手段。本文综述了钛合金锻件微织构产生原因以及潜在的负面影响,并讨论了其控制措施。最后,针对改善钛合金锻件组织均匀性进行了展望。

关键词 钛合金晶体取向微织构均匀性稳定性    
Abstract

Due to their excellent performance, near α and α + β dual-phase titanium alloys are critical materials in aerospace engineering. Enhancing the performance stability of titanium alloy forgings has become a focal point of research in engineering applications. However, the microtextures within these forgings significantly affect key properties such as fatigue resistance, which limits the overall performance of titanium alloy forgings. Recent studies indicate that optimizing the hot working process to improve the crystallographic orientation and microstructure uniformity is an effective means of enhancing alloy performance. This study reviews the origins of microtextures in titanium alloy forgings, their potential negative effects, and the optimization processes involved. Finally, the study presents several research guidelines aimed at improving the microstructural uniformity of titanium alloy forgings.
