钛合金热变形机制及微观组织演变规律的研究进展

Progress on Hot Deformation Mechanisms and Microstructure Evolution of Titanium Alloys

综述了当前国内外钛合金在热加工过程中的变形机制及微观组织演变规律方面的研究成果。主要讨论了α,α+β和β钛合金在β区、α区或α+β两相区热变形的流变曲线特征,应力指数和变形激活能参数,α相和β相的变形方式、再结晶和回复以及α+β两相组织的球化等组织演变机制及规律。

Research findings of the hot deformation mechanisms and microstructure evolution of titanium alloys abroad and at home currently are summarized. Characteristics of hot deformation curves, stress exponents and apparent activation energy parameters for α, α-β and β titanium alloys deforming in β, α or α＋β fields, deformation patterns and recrystallization and recovery of α and β phases, globularization of a and β lamellar structure were discussed mainly.
