Zusammenfassung:	A method of manufacturing a crystalline aluminum-iron-silicon alloy and a crystalline aluminum-iron-silicon alloy part. An aluminum-, iron-, and silicon-containing composite powder is provided that includes an amorphous phase and a first crystalline phase having a hexagonal crystal structure at ambient temperature. The composite powder is heated at a temperature in the range of 850° C. to 950° C. to transform at least a portion of the amorphous phase into the first crystalline phase and to transform the composite powder into a crystalline aluminum-iron-silicon (Al-Fe-Si) alloy. The first crystalline phase is a predominant phase in the crystalline Al-Fe-Si alloy.
