Microstructure and Mechanical Properties of Titanium Alloys
The influence of microstructure was tested on the mechanical properties in tensile tests, on hardening and softening behaviour and on fatigue time. Attention was chiefly given to the alloy Ti-6Al-4V. For studies of yield point superelevation and of the E-module the alloys Ti-8.8Al-4V, Ti-8.6Al and Ti-4Al were also used. The influence of grain, hardening and texture on the mechanical properties was also studied in tensile tests. Fatigue and alternate deformation tests were carried out in vacuum and in air to study hardening and softening behaviour, to determine low cycle fatigue (LCF) and high cycle fatigue (HCF) and to observe crack formation. Additional aspects included: a) study of yield point superelevation in tensile tests, b) influence of the stress-induced martensitic transformation beta -> alpha ' on the behaviour of the alloy, c) influence of the Bauschinger Effect on cyclic deformation, and d) special effects arising from power-driven testing.
