Abstract

The room temperature elastic-plastic fracture toughness of additively manufactured (AM) Ti 6Al- 4V was characterized by means of Elastic Compliance (EC) tests on Charpy-type fatigue precracked and side-grooved specimens. Various fabrication and material conditions were investigated: such as as-built and hot isostatically pressed specimens, non-supported and supported specimens, different values of scan length. The results, although strictly not fully compliant with ASTM E1820-18ae1, can be considered representative of the fracture toughness of the material in the different conditions, and compare favorably with literature data for both non-AM and AM Ti-6Al-4V. Additional analyses were conducted with another single-specimen approach (Normalization Data Reduction) and were compared with EC results.
