Research indicates that post-processing heat treatments are critical for optimizing the mechanical behavior of additively manufactured alloys. For instance, studies on uranium-niobium alloys have shown that recrystallization treatments can transform the microstructure to achieve wrought-like properties, ensuring greater consistency and performance in the final component (Wu et al., 2017). This highlights the importance of integrating thermal processing into the additive manufacturing workflow for critical applications.
