In the present study, susceptibility of a high manganese TWIP steel to stress corrosion cracking (SCC) in a 3.5% NaCl solution was investigated using slow strain rate tests (SSRT), constant load (CL) tests and fractography. Strain rates employed for SSRT were in the range of 10-06 - 10-08 s-1. The specimens tested in air revealed a ductile type of failure, whereas those tested in the corrosive solution exhibited a brittle feature that is attributed to stress corrosion cracking. SCC was observed at a relatively low strain rate of 10-07s-1.
