Microstructure, phase formation and properties of rapid solidified Al–Fe–Cr–Ti alloys

Improvements in the mechanical strength of Al–Fe–Cr–Ti alloys have been demonstrated when non-equilibrium microstructures are developed. This paper investigated the effect of cooling rate and composition on the phase formation, microstructure and properties of new Al 96.6 Fe 1.5 Cr 1.7 Ti 0.2 and Al 91.6 Fe 4.9 Cr 2.2 Ti 1.3 (at.-%) alloys. Wedge-shaped samples produced by suction casting were characterised by optical, scanning electron...
