Strain-controlled fully reversed fatigue testing, or strain-life provides critical information on material lifetime and damage response. Strain-life data in hydrogen gas environments is missing the literature could provide valuable insights into effects mechanical response of metals such as steel. We adapted existing hydrogen-gas-environment mechanical-testing equipment, which had been designed...
