Abstract:
Additive manufacturing is enabling the expansion of the personalization of bone and joint replacements to match the exact needs of individuals. However, the success of 3-D printing of medical device alloys such as Ti-6Al-7Nb and Ti-6Al-4V depends upon non-isothermal deposition and cooling processes being able to produce acceptable microstructures defined by set standards. In this work, we develop and implement metallographic preparation and analysis techniques to show that desirable fine structured alpha+beta phase morphologies can be created by additive manufacturing. We further show how low-hazard etchants can effectively replace the use of hydrofluoric acid for revealing microstructures in additively manufactured alloys.
