| Abstract Scope |
The mechanical properties of a laser melting deposited (LMD) Ti–6Al–2Zr–Mo–V alloy are investigated using the nanoindentation and micro-cantilever Bending methods. The results show that hardness and reduced modulus of individual phases made by additive manufacturing are comparable with those made by conventional casting or forging methods. The mechanical difference between α and β phases associated with the crack path will be discussed. This work highlights the comparison of properties of individual phases made by various manufacturing methods and elucidates the relationship between mechanical contrast between phases and corresponded crack propagation mechanisms. |
