Abstract

In this work, the effect of processing conditions on microstructure and mechanical properties of Fe–Al–Si alloys is studied. The microstructure and mechanical properties during each step of processing consisting of mechanical alloying and spark plasma sintering are characterized by means of light microscopy, scanning electron microscopy, x-ray diffraction and micro/nano hardness measurements. Effect of mechanical alloying conditions (especially milling time) on chemical/phase composition, microstructure and overall mechanical properties of spark plasma sintered samples is presented and discussed.

Keywords: Powder metallurgy; mechanical alloying; spark plasma sintering; iron aluminide; iron silicide
