Les essais de fatigue consistent a etudier le comportement sous sollicitation cyclique des materiaux et a en determiner sa resistance. L’objectif de cet article est de presenter les principales methodes d’essais qui ont ete developpees, soit pour comparer des materiaux et des procedes de fabrication, soit pour obtenir les donnees necessaires a la prevision des durees de vie de composants soumis a un chargement cyclique. Cet article arbore tout d’abord les definitions liees aux essais de fatigue. Il se focalise ensuite sur la description des differentes methodes employees pour determiner la resistance a l’amorcage en endurance des materiaux ou des structures.

Les phases MAX sont des carbures et nitrures ternaires qui associent remarquablement des proprietes typiques a la fois des metaux et des ceramiques. Ils ont une bonne conductivite thermique et electrique, une usinabilite, ainsi qu'une tolerance a l’endommagement et une resistance a l’oxydation a haute temperature. Cette combinaison unique leur confere un potentiel fort comme materiaux structurels et fonctionnels, notamment en environnement severe (hautes temperatures, oxydation, irradiation...). Cet article traite des differentes voies d’elaboration, proprietes, applications et de leur positionnement face aux ceramiques techniques et aux alliages metalliques hautes temperatures existants.

La fatigue, c'est-a-dire la rupture de structures mecaniques sous l'effet de chargements cycliques, demeure une gageure technologique considerable, car elle survient de facon inattendue lorsque la structure fonctionne apparemment dans un regime stabilise et sur, sans signe exterieur de deterioration mecanique. Apres avoir presente ce contexte et les methodes classiques de controle de la fatigue par emission acoustique (EA), une nouvelle methode non destructive de detection specifique de la propagation de fissures de fatigue est exposee a partir de multiplets acoustiques : signaux d’EA repetitifs, aux formes d'ondes quasi identiques. Des perspectives de controle en service sont ensuite proposees.
