| Abstract Scope |
This study investigates the interplay between size, geometry, and temperature and their effects on the mechanical properties of Additively manufactured titanium alloys (Ti-6Al-4V). Quasi-static testing was conducted at ambient, 250, and 450 degrees Celsius temperatures, showing a decrease in elongation and an increase in strain-softening rates as sample thickness is reduced. Furthermore, comparisons made between test samples of flat and round samples indicated a further decrease in elongation and increased strain-softening for thin round samples , respectively. It was also noted that this trend becomes more apparent as the temperature is raised from 250 to 450 degrees Celsius. To determine the driving mechanisms responsible for this phenomenon, a microscopic examination of texture and grain morphology was conducted alongside surface roughness data as functions of sample thickness and geometry. |
