The quaternary Al75Mn10Fe5Si10 alloy was synthesized by induction melting, melt spinning and subsequent annealing. The melt spun sample shows the multiply twinned nodular-type microstructure. These plates surround an icosahedral seed of the nodule. Annealing induces relaxation/transformation of the seeds due to diffusion process. We studied the electrical properties of all the three states (as-cast, quenched and annealed) of Al75Mn10Fe5Si10 alloy. The results are discussed in the framework of Ziman-Faber theory.
