Se situant au centre des appareils de voie, il a pour objectif d\u2019assurer la continuit\u00e9 des itin\u00e9raires qui se croisent.<\/p>\n<p>De par sa fonction, le c\u0153ur\u00a0de voie est soumis \u00e0 des contraintes importantes telles que les fortes charges\/pressions et les impacts, entra\u00eenant des usures de type d\u00e9formation et arrachement.<\/p>\n<p>D&#8217;un point de vue m\u00e9tallurgique, une des solutions permettant de r\u00e9pondre \u00e0 ce type de sollicitations est l&#8217;acier aust\u00e9nitique Hadfield \u00e0 13% de mangan\u00e8se.<\/p>\n<p>Les c\u0153urs de voie prennent vie au sein de fonderies.<\/p>\n<p>Pendant la fabrication, il est possible que des d\u00e9fauts de fonderie apparaissent.
