Abstract Based on state equation that stress is a function of strain and strain-rate, the differential constitutive equation during superplastic tensile deformation is deduced, and then the mechanical meaning of strain hardening index in the equation is interpreted. The constraint equation of strain hardening index is deduced, strain hardening indexes in typical deformation paths are defined, and their interrelations are gotten. Measuring formulae of strain hardening indexes in typical deformation paths and accurate measuring methods by numerical simulation are deduced. According to them, strain hardening indexes are experimentally measured, and measuring methods & results are elaborately analyzed. The results prove that: not only does strain hardening index be non-constant, but also has close relations with the changing rule of strain and deformation path; not only does strain hardening index have close relations with deformation path, but also with adopted measuring formula. Therefore, as strain hardening index is quoted, its corresponding deformation path should be shown clearly; when strain hardening index is measured, the measuring formula of its corresponding deformation path should be adopted.

Key words: superplasticity strain hardening index mechanical analysis experimental measure
