Evolution of Substructures in Additively Manufactured Pure Titanium

The investigation of substructures in additively manufactured metals constitutes a crucial yet underexplored area of research. In this study, we undertake a comprehensive analysis of dislocations and twinning in as-deposited pure titanium, establishing their correlation with thermal conditions. Specifically, we focus on the < a > and < a + c > dislocations, which exhibit the smallest and largest shear stress, respectively. Additionally, we meticulously characterize the < 10-1-2 > twin with the smallest shear strain, identifying its presence in both the top and bottom positions. Our findings provide valuable insights into the substructure evolution of additively manufactured pure titanium, offering significant implications for material processing and design in additive manufacturing applications.
