, Les résiliences du mur 5 / 50 montrent des valeurs légèrement supérieures à celles du mur 7,5 / 75. Néanmoins, le niveau d'énergie de rupture absorbée à -196°C est en moyenne de 20 J, ce qui n'est pas très performant par rapport aux données du certificat de soudage (>40 J), fabriqués par HIP (Hot Isostatic Pressing, Les résultats des essais de résilience réalisés à -196 et 20°C sont présentés à la figure 106 avec des barres d'erreur de +/-3 écarts types
