A review of the microstructure and tensile behavior of additively manufactured metastable β Ti alloys

Abstract

This review summarizes and critically discusses the current knowledge on the microstructures and tensile properties of metastable β Ti alloys fabricated by selective laser melting and laser metal deposition techniques. The effects of post‐heat treatments are also addressed. The spatial variations in the microstructure and properties are linked with the processing parameters. The review also compares the additively manufactured and post heat‐treated metastable β Ti alloys with their wrought counterparts. It highlights the research questions for further investigations.
