钛合金的定量研究进展

Development of Quantitative Research in Titanium Alloys

钛合金因其优异的综合性能受到国内外研究者和使用者的青睐,其基础和应用技术研究的核心是针对"合金成分-工艺-组织-性能"之间关系的研究。以往钛合金的成分设计、工艺-组织-性能间关系的研究都是定性的,获得了良好的结果,并得到了实际应用。"合金成分-工艺-组织-性能"之间的定量关系研究是近几年国内外钛合金研究的一个热点,已取得一定的进展。综述了高强钛合金的成分定量设计、工艺-组织-性能间定量关系建立的研究进展,主要包含高强钛合金成分的定量设计方法、微观组织的定量表征方法、组织与性能定量关系建立、工艺与性能的定量关系建立等,并通过实际验证。

Because of excellent; comprehensive properties, titanium alloys draw wide attentions from researchers and us- ers. The key research direction is the relationship among composition, processing, microstructure and properties. The de- sign of composition and the relationship among processing, microstructure and property were qualitativly analyzed in the past, and good results were achieved. In recent years, the quantitative relationships among composition, processing, mi- crostructure and properties were studied, and some results were achieved. This paper interviews the development of quan- titative design of composition for high strength titanium alloy and the research of quantitative relationship among process- ing, microstructure and property, mainly including the quantitative design method of composition for high strength titanium alloy, quantitative characterization for microstructure, quantitative relationship between microstructure and properties and quantitative reXationship between processing and properties, and the quantitative relationships, were tested and verified.
