A study was made to obtain a better understanding of the mechanism of hydrogen embrittlement through the study of the gas content of embrittled specimens. The specimens consisted of rings of 4130 steel, 2.54 cm in diameter, 0.9 cm long, and 0.08 cm wall thickness. They were electrolytically charged in several different solutions: 10% solution of sodium hydroxide, cyanide copper and cadmium plating baths, and chromic acid type of chromium plating bath. The measure of the embrittlement was taken as the decrease in either tbe crushing load or the deformation at failure, as compared to a control specimen. Deuterium embrittled 4130 steel, but to a much smaller extent than did hydrogen. On the other hand, specimens embrittled in solutions made with heavy water contained a larger, volume of gas (deuterium) than specimens similarly treated for the same length of time in an ordinary water solution.
