| The effect of processing conditions on microstructure and mechanical properties of mechanically alloyed Fe20Al20Si (wt%) intermetallic compound was examined. The microstructure, phase composition and mechanical properties after various durations of mechanical alloying were characterized and optimum conditions of mechanical alloying were used for spark plasma sintering. Spark plasma sintering parameters were also optimised so that correctly sintered samples preserved phase composition and mechanical properties of milled powders. |
