Description	Under mechanical loading, at room temperature, the stainless steel AISI 321 is unstable and undergoes a phase transformation austenite->martensite. The heterogeneity of the structure evolves under mechanical loading, what has been confirmed by X-ray diffraction analysis, by metallographic analysis as well as by microhardness measurements, on samples submitted to various types of loading: compression and tensile tests and also friction tests (done on pin-on-disk apparatus in distilled water). The behaviour of unstable steel AISI 321 under mechanical loading was compared with the one of the duplex steel 22-05 that possess a heterogeneous, stable microstructure, composed of 50 % of austenite and 50 % of ferrite. (en) Sous sollicitation mécanique, a 20°C, l'acier inoxydable AISI 321 est instable et subit une transformation structurale austénite->martensite. L'hétérogénéité de la structure évolue sous sollicitation mécanique, ce qui a été confirmé par analyse aux RX, par étude métallographique ainsi que par mesure de microdureté, sur des échantillons soumis a divers types de sollicitations: essais de traction, de compression, et de frottement effectués sur un tribometre de type bille-disque. Cette instabilité structurale pourrait limiter l'emploi de cet acier dans les nombreux domaines ou il est utilisé. Sous frottement, l'influence des parametres mécaniques (force normale, vitesse de frottement, temps) sur la transformation martensitique de l'AISI 321 est étudiée avec l'eau pour milieu environnant. Le comportement de l'acier AISI 321 instable sous sollicitation mécanique est différent de celui de l'acier duplex 22-05 qui possede une microstructure hétérogene, stable, composée de 50 % d'austénite et de 50% de ferrit
