| Abstract Scope |
Titanium alloys are critical structural materials with high specific strength, excellent toughness, and high corrosion resistance. These properties of titanium alloys can be manipulated by tuning microstructure evolution via different heat treatments. In this work, we used the 2D scanning electron microscopy (SEM) and 3D focused ion beam- scanning electron microscopy (FIB-SEM) tomography to quantitatively study the microstructural evolution during the post-heat treatment for the additively manufactured Ti-5Al-5V-5Mo-3Cr (wt.%, Ti-5553) alloy. The influence of the aging temperature on the ⍺ microstructure during the post heat treatment was systematically investigated. Refined, more-refined, and super-refined ⍺ microstructure with different number densities were successfully generated. We will introduce the critical roles of post heat treatment on tuning the microstructure in additive manufactured Ti-5553. |
