Fatigue crack growth in Selective Laser Melted Ti-6Al-4V

This research investigates the effect of a varying build orientation and different heat treatment on the crack propagation properties of SLM Ti-6Al-4V. Both crack propagation rate and direction are investigated. Fatigue tests are performed with a constant cyclic load and single edge notch specimens. Ten unique types of specimens were tested by...

Fatigue Crack Initiation Behaviour of Additive Manufactured Ti-6Al-4V

This master thesis investigates the effect of surface morphology of Selectively Laser Melted Ti-6Al-4V on fatigue performance. The literature study performed here iden- tifies roughness as one of three major causes for the decreased performance of the additive manufactured alloys (along side porosity and residual stresses). In order to eliminate...

Fatigue of additively manufactured Ti-6Al-4V using sub-sized samples

<br/>Additive manufacturing (AM) is quickly becoming one of the more popular methods to manufacture components made of Ti-6Al-4V in the aerospace and automobile industry due to its flexibility in producing complex geometries and reducing tooling costs. As the world of additive manufacturing is still relatively young, there is no globally...
