Two opposing views exist to account for the SCC of the near-..cap alpha.. Ti-8Al-1Mo-1V, namely preferential anodic dissolution and hydrogen-induced cleavage. This communication provides support for the latter by comparing the fracture surfaces produced by SCC and by slow-strain-rate hydrogen embrittlement, a process known to occur by mechanical fracture. In addition, it demonstrates that the often complex fracture surfaces can be readily interpreted in terms of a cleavage model.
