The invention provides a characterization method for deformation characteristics of a TiN alloy, and relates to the technical field of titanium alloy material processing and preparation. According to the deformation damage constitutive equation suitable for the TiN alloy, the function relation is established through the damage variables and the strain, the stress-strain relation in the deformation process of the TiN alloy is represented through the damage variables, and the deformation characteristics of the TiN alloy can be reflected more truly; and the effective strain range and the fracture stress of the TiN alloy within a certain deformation condition range are predicted. The damage constitutive equation adopted by the method is superior to a traditional Zener-Hollomon parameter equation, and the deformation characteristics of the TiN alloy can be represented more accurately and specifically. 本发明提供一种TiN合金变形特性的表征方法，涉及钛合金材料加工制备技术领域。本发明提出了一种适用于TiN合金的变形损伤本构方程，利用损伤变量与应变建立函数关系，采用损伤变量表征TiN合金变形过程中的应力-应变关系，可以更加真实的
