Effect of the Strain Rate on the Fracture Behaviour of High Pressure Pre-Charged Samples
<b> </b>The aim of this work is to study the effect of the displacement rate on the hydrogen embrittlement of two different structural steels grades used in energetic applications. With this purpose, samples were pre-charged with gaseous hydrogen at 19.5 MPa and 450 °C for 21 h. Then, fr...
