The Effect of Simultaneous Si and Ti/Mo Alloying on High-Temperature Strength of FeAl-Based Iron Aluminides.

The effect of phase composition and morphology on high-temperature strength in the compression of Fe-Al-Si-based iron aluminides manufactured by casting was investigated. The structure and high-temperature strength in the compression of three alloys-Fe28Al5Si, Fe28Al5Si2Mo, and Fe28Al5Si2Ti-were studied. Long-term (at 800 °C for 100 h) annealing was performed for the achievement of structural stability.
