fis-1622	Matsuda, Yuta; Nishiguchi, Hiroshi; Fukuda, Takayuki	Effects of large amounts of hydrogen on the fatigue crack growth behavior of torsional prestrained carbon steel	2015	10	.pdf	application/pdf	4812	291	58	Hydrogen content, CH, increased with torsional prestrain for both S10C and S25C steels; the CH of the torsional prestrained S25C steel precharged with hydrogen was lower than that of S10C at the same torsional prestrain. A hydrogen content threshold was found; hydrogen content above this limit enhances the growth of the non-propagated crack, even for metals with lower hardness (HV < 200).	cache/fis-1622.pdf	txt/fis-1622.txt
