摘要：
Due to their attractive combination of high strength along with great ductility, duplex stainless steels (DSS) are often being used as pressure vessels or underwater pipelines. The use of DSS in services combined hydrogen and mechanical load can lead to hydrogen embrittlement. The susceptibility to hydrogen embrittlement is directly related to the interaction between defects (traps) and hydrogen. Hydrogen effects are being studied by a thermal desorption spectrometry (TDS) process. In this research we determine the mechanical properties of DSS with hydrogen at high strain rates. Hydrogen trapping and its effect on the mechanical properties are discussed in details. (C) 2016 The Authors. Published by Elsevier Ltd.
