Effect of surface roughness on fatigue performance of additive manufactured Ti–6Al–4V
TL;DR: In this article, the effects of inherent surface roughness on the fatigue life of Ti-6Al-4V parts were investigated. And the results showed that the fatigue properties of these materials are dominated by roughness effects, and a simple model based on an equivalent initial flaw size was formulated.

Microstructure and Mechanical Properties of High Strength Two-Phase Titanium Alloys
TL;DR: The main types of microstructure are (1) lamellar - formed after slow cooling when deforma- tion or heat treatment takes place at a temperature in the single-phase β-field above the socalled beta-transus temperature Tβ (at which the α+β→β transformation takes place), consisting of colonies of hexagonal close packed (hcp) α-phase lamellae within large body centered cubic (bcc) β-phase grains of several hundred microns in diameter, and (2) equiaxed -formed after deformation in
