Abstract Scope |
A combination of high energy laser and powder feeding control in DED machine allows to enable a rapid alloy prototyping strategy that expands the alloy design window by additive manufacturing. However, different characters of elemental powders make a difficulty to get an optimal processing condition for rapid alloy prototyping that results into the non-homogeneous matrix. Therefore, complete melting and mixing of elemental powders to obtain a homogeneous matrix during AM can be a challengeable issue. In this study, Ti-Nb-Zr-Sn bio-titanium alloys are designed by adapting rapid alloy prototyping strategy using Ti, Zr, Nb, and Sn elemental powders. Microstructure analysis and tensile tests were performed to confirm the compositional homogeneity and mechanical properties of the Ti-Nb-Zr-Sn alloys fabricated through rapid alloy prototyping, and the correlation between the microstructure and mechanical properties will be discussed. |
