Evaluation of the microstructure and mechanical properties of a Ti-6Al-4V shell
We describe work performed to evaluate the mechanical properties of a Ti-6Al-4V shell. Of particular interest were the mechanical properties at strain rates up to approx.10 s/sup -1/. Two tasks were undertaken during this project. The first was a fundamental study of the deformation mechanisms in Ti-6Al-4V to identify the underlying rate controlling processes. The second task was a thorough evaluation of an actual Ti-6Al-4V shell, with the intent to characterize the microstructure and mechanical properties of a manufactured component. This latter task is the focus of this report. A simple constitutive law is proposed to describe the strain hardening and strain-rate sensitivity of the shell material. A much more extensive and physically based formulation for the constitutive behavior is presented in the Appendix.
