real shift in the value of transition temperature for ½ Charpy induced by HE, but do not show a change in the case of standard Charpy. A dependence on the thickness of the specimens can therefore be highlight. Due to the increased use of high pipe steel (X80 and higher), further researches will be held to study the effect of HE on the value of transition temperature.
