Sintering of Alloyed $Ni_3Al$ Starting from Mechano-composites Powders

Considering the idea that some properties, especially the mechanical properties of $Ni_3Al$ at ambient temperature can be improved by adding of some substitutional/interstitial elements, our goal was to obtain these materials starting from mechano-composites powders. In this aim, using mechanical alloying techniques three type of mechano-composite powders starting from elemental powders were obtained. Then, by reactive sintering in argon atmosphere at temperature over $900^{\circ}C$, alloyed $Ni_3Al$ materials were realized. This paper presents our research results regarding the microstructural aspects and phase formation in obtained materials.
