Microstructural evolution and mechanical pr<strong>op</strong>erties of<br />
AlMg/AlN composite materials obtained "in-situ"<br />

In this paper characteristics of an AlMg/AlN composite<br />
produced “in-situ” and processed in a flowing N 2 atmosphere is<br />
investigated. Some critical parameters such as the<br />
manufacturing process temperature, the percentage of the<br />
magnesium consumed, the flowing reactive gas flow and the<br />
time for completing the manufacturing are considered as<br />
variables for the parametric investigation. Moreover, the effect<br />
of different amount of Mg employed has been also investigated,<br />
since Mg acts as a catalyst at the surface both for the gas/liquid<br />
and solid/liquid systems.<br />
Traditional methods were used for the basic characterization of<br />
the composite. The microstructure of the composite was<br />
investigated by <strong>op</strong>tical and scanning electron microsc<strong>op</strong>y (OM,<br />
SEM). SEM analysis was performed in order to observe the<br />
microstructural evolution as a function of the Mg content and to<br />
identify some reasons of the presence of porosity or any<br />
irregularities within the metal matrix. The evolution of<br />
mechanical pr<strong>op</strong>erties, in terms of micro hardness, at different<br />
percentage of Mg were monitored. By EDS technique the<br />
distribution of the elements was obtained.<br />
Furthermore, employing an <strong>op</strong>timization process, uniform<br />
