Abstract

Titanium

Mechanical properties

Cryomilling

Microstructure

Nanostructured materials

The room temperature tensile behavior of cryomilled and quasi-isostatically forged commercially pure (CP)-Ti was investigated. Enhanced tensile strength (yield strength = 840 MPa, ultimate tensile strength = 902 MPa) in combination with high ductility (elongation to failure = 27.5%) was observed. This mechanical behavior is rationalized on the basis of processing history, microstructure (multimodal grain distribution, high-angle grain boundaries, high dislocation density) and chemistry. Relevant mechanisms are discussed and the results compared to those reported in earlier studies.
