Abstract

Based on the example of testing the two-phase high-strength titanium alloy VT22 and submicrocrystalline commercially pure titanium VT1-0 with different initial structures, the basic regularities are found in the variation of the mechanical properties under specific impact with oscillation loading on the elastic section of stress-strain curves. It is experimentally shown that for the two-phase high-strength titanium alloys, the addition of specific impact with oscillation loading on the elastic section of stress-strain curves can be used as a technological method for improving the initial mechanical properties, in particular, ductility.

Kurzfassung

Basierend auf der Prüfung der zweiphasigen hochfesten Titanlegierung VT22 und submikrokristallinem kommerziell reinem Titan VT1-0 mit verschiedenen Ausgangsgefügen wurden grundlegende Regelmäßigkeiten unter der Variation der mechanischen Eigenschaften gefunden, und zwar unter Vibrationsschockbeanspruchung im elastischen Bereich der Spannungs-Dehnungs-Kurven. Es wurde experimentell gezeigt, dass für die zweiphasigen hochfesten Titanlegierungen die Zugabe einer Vibrationsschockbeanspruchung im elastischen Bereich der Spannungs-Dehnungs-Kurven als technisches Verfahren genutzt werden kann, um die ursprünglichen Materialeigenschaften, insbesondere die Duktilität, zu verbessern.
