MM 52.1: Vortrag

Microstructure-engineering of near-α titanium alloys — •Stefanie Sandlöbes1,2, Zahra Tarzimoghadam2, Sandra Korte-Kerzel1, and Dierk Raabe21Institut für Metallkunde und Metallphysik, RWTH Aachen University, Aachen, Germany — 2Max-Planck-Institut für Eisenforschung GmbH, Düsseldorf, Germany

Lean alloying of the beta-stabilizing elements Fe and Mo to titanium in combination with appropriate heat treatments enables one to manipulate the microstructure. Consequently, the mechanical properties can be tailored covering a broad range from low yield strength and high ductility to high yield strength and medium ductility. By applying multi-scale characterization of the mechanical properties and microstructures it is shown that local segregation and partitioning phenomena on the nano-scale are causing local allotropic and martensitic transformations and significantly alter the active deformation mechanisms.
