On the mechanical behaviour of titanium alloy TiAl6V4 manufactured by selective laser melting: Fatigue resistance and crack growth performance
Stefan Leuders,M. Thöne,Andre Riemer,Thomas Niendorf,Thomas Tröster,Hans Albert Richard,Hans Jürgen Maier +6 more
TL;DR: In this article, the microstructure-defect-property relationship under cyclic loading for a TiAl6V4 alloy processed by selective laser melting is investigated. And the results show that the micron sized pores mainly affect fatigue strength, while residual stresses have a strong impact on fatigue crack growth.
