An electron microscopy characterization of three antifriction materials based on the AlSn system was carried out. AlSn20Cul, AlSn15Si3Cu1 and AlSn15Si3Cu1Mn0.5 both in the as-cast and in the rolled and annealed condition were considered in order to investigate the microstructure and the influence of addition of minor elements. Results show that the microstructure is characterized by the presence of Snrich islands containing the intermetallic Al3Cu12Sn phase. Addition of Si causes the formation of small Si particles both associated with the Sn-based islands and isolated in the matrix. Mn addition induces an increase in the tensile properties of the material via a work-hardening mechanism.

Abstract
An electron microscopy characterization of three antifriction materials based on the AlSn system was carried out. AlSn20Cul, AlSn15Si3Cu1 and AlSn15Si3Cu1Mn0.5 both in the as-cast and in the rolled and annealed condition were considered in order to investigate the microstructure and the influence of addition of minor elements. Results show that the microstructure is characterized by the presence of Snrich islands containing the intermetallic Al3Cu12Sn phase. Addition of Si causes the formation of small Si particles both associated with the Sn-based islands and isolated in the matrix. Mn addition induces an increase in the tensile properties of the material via a work-hardening mechanism.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
