Abstract

Ti-6Al-4V alloy has specific properties to meet the industrial application. The present work discusses the variant selection in the thermally treated Ti-6Al-4V alloys processed by laser metal deposition (LMD). It is found that the variant selection is strengthened by thermal cycles. The thermally treated Ti-6Al-4V alloy has the grain boundary α (αGB) and Widmanstätten microstructure. And the Widmanstätten microstructure develops from α grain boundaries (αWGB) and follows the Burgers boundary orientation relationship (BOR). This work explores the variant selection when the LMD-ed Ti-6Al-4V undergoes the thermal treatment.
