Abstract Scope |
Titanium alloys are critical structural materials with excellent mechanical properties, such as high strength and great toughness. These mechanical properties of titanium alloys can be tuned by the manipulation of microstructure evolution during different heat treatment. In this work, we used the advanced scanning electron microscopy (SEM) and MIPAR image analysis software to quantitatively analyze the ⍺ precipitate microstructure after 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 ⍺ precipitate microstructure during the post heat treatment was systematically investigated. Different fine-scaled ⍺ microstructures 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 alloy.
