摘要: Abstract The effect of solution-treated temperature on hydrogen embrittlement 17-4 PH stainless steel is investigated. Electrochemical charging and slow strain rate tensile tests were used to calculate the index susceptibility embrittlement. Fracture morphology microstructure observed by scanning electron microscope, optical microscope transmission microscope. results show that as increases from 890 °C 1090 °C, firstly decreases then increases. Based experimental results, it deemed determined result a combined prior austenite grain size copper precipitation. In addition, permeation test reveals hydrogen-induced cracking closely related diffusion behavior in alloys.
