L. Bouffier-analytique, pour tous les éléments excepté l'hydrogène, les gaz nobles et les éléments instables. La haute résolution de l'appareil des laboratoires EAG de Toulouse permet de mesurer des concentrations de l'ordre du pourcent jusqu'à l'ultra trace (ppb) avec une incertitude de mesure de +, 20% (source : Evans Analytical Group). C'est une technique fiable mais plus onéreuse que l'ICP

L. and «. Normales, des éléments dont la concentration est estimée supérieure à 0.1 % pds ont été analysées dans les laboratoires du Service Central d'Analyse

. Le-principe-de-cette-technique-d, analyse présente de nombreuses similitudes avec la technique GDMS (ionisation de l'échantillon en l'injectant dans un plasma d'argon qui est ensuite analysé soit par un réseau polychromateur (méthode optique), soit par spectrométrie de masse) mais reste moins performante pour les éléments trace (<100 ppm) En effet, le seuil de détection de cette technique est de l'ordre de 100 ppm qui permet néanmoins l'analyse de la quasi-totalité des éléments de l'alliage étudié

. Comme-mentionné-précédemment, P. De, and S. , ont été réalisées par GDMS. On note que les concentrations sont relativement homogènes dans chaque coulée, ce qui permet de considérer des teneurs moyennes pour nos modèles et

L. Bouffier, On note à l'inverse que le chrome ou le fer ont une influence beaucoup plus faible (des variations supérieures au pourcent affectent moins le chemin de solidification que des variations de l'ordre du dixième de pourcent d'éléments comme le Si

M. Un-alliage and . Quasiment-assimilable-À-un-ternaire-ni, Cr-Fe présente un intervalle de solidification beaucoup plus étroit et une température de solidus sensiblement plus élevée, Il est probable que cet alliage est moins exposé au risque de fissuration à chaud étant donné son petit intervalle de fragilité en température (BTR)
