Title: Phase partitioning in a novel near equi-atomic AlCuFeMn alloy,
Abstract: A novel low cost, near equi-atomic alloy comprising of Al, Cu, Fe and Mn is
synthesized using arc-melting technique. The cast alloy possesses a dendritic
microstructure where the dendrites consist of disordered FCC and ordered FCC
phases. The inter-dendritic region is comprised of ordered FCC phase and
spinodally decomposed BCC phases. A Cu segregation is observed in the
inter-dendritic region while dendritic region is rich in Fe. The bulk hardness
of the alloy is ~ 380 HV, indicating significant yield strength.
