A differential dilatometer capable of detecting volume changes of 1 part in 10/sup 5/ in specimens exposed to a hydrogen atmosphere at 6.2 MPa and 500/sup 0/C is described. The swelling of an alloy under hydrogen-attack conditions can be studied over a wide range of hydrogen pressures and temperatures by use of a single specimen.
