Stress corrosion tests of an amorphous FeCrNiW alloy and wrought crystalline AISI 304 stainless steel (SS) alloys in boiling MgCl/sub 2/ have demonstrated that the amorphous FeCrNiW alloys exhibit stress corrosion properties equal to or better than solution-annealed AISI 304L SS. Static load bend tests were conducted in boiling MgCl/sub 2/ both on a sputter-deposited FeCrNiW alloy and on solution-annealed low-carbon and sensitized high-carbon AISI 304 SSs. The time to failure was determined as a function of the maximum tensile stress. Fracture of the amorphous material occurred by rapidly advancing cracks that are thought to initiate at corrosion pits, while AISI 304 SS failed by conventional stress corrosion cracking (SCC).
