    Abstract - (Show below) - (Hide below)

    La présente Norme internationale spécifie une méthode de détermination micrographique de la grosseur apparente du grain ferritique ou austénitique des aciers. Elle décrit les méthodes de mise en évidence des joints de grains et d'estimation de la grosseur moyenne de grain d'un échantillon ayant une distribution granulométrique unimodale. Bien que les grains soient de forme tridimensionnelle, le plan de la préparation métallographique peut couper un grain en tout point, passant par un coin du grain ou au travers du diamètre maximal du grain ou entre les deux, produisant de ce fait une gamme de grosseurs de grain apparentes sur le plan bidimensionnel, même dans le cas d'un échantillon présentant une grosseur de grain parfaitement cohérente.
