A Constitutive Structural Parameter for the Work Hardening Behavior of Additively Manufactured Ti-6Al-4V
- Sandia National Lab. (SNL-CA), Livermore, CA (United States)
The mechanical behavior of Ti-6Al-4V produced by additive manufacturing processes is assessed based on a formulation developed from the Kocks-Mecking relationship. A constitutive parameter derived for the microstructure is characteristic of the work hardening behavior determined by the plastic strain between the proportional limit and the strength at the instability point. The varied plasticity behavior associated with surface and build direction effects can be evaluated with this approach as presented for the case of Ti-6Al-4V under uniaxial tension.
