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.
