Purpose: The aim of this paper is to determine the influence of the mechanical milling process on the structure of Al67Ti25Fe8 alloy. Design/methodology/approach: The powders of the Al67Ti25Fe8 alloys were obtained by mechanical alloying method in a planetary Fritsh Pulverisette 5 mill. In order to investigate the structure scanning electron microscopy were used. Phase transformations were determined by means of diffractometer. The cross-sectional microstructure evolution and element distribution of Al67Ti25Fe8 powder alloys were investigated using backscattering electrons of SEM. The distribution of powder particles was determined by a sieve analysis. Findings: The laboratory test show that, by using the mechanical alloying method, one can produce Al67Ti25Fe8 alloys with intentional chemical constitution and desirable structure. Inside the milling materials didn't find some impurities and undesirable phases. Research limitations/implications: Property of Al67Ti25Fe8 alloys correction is possible by refinement of grains and modification of phases composition. All of the presented experiments in this article are made on a laboratory scale. Continuation of the investigations in the field of sintering alloyed powders to obtained massive materials is foreseen. Practical implications: In the nearest future the producing of bulk materials characterized by better properties in comparison with traditional materials will take place not only in the laboratory scale and move to the industry. Originality/value: : In addition a good microstructural homogeneity and first of all mechanical properties was achieved, also practical application will be possible. The Al-Ti-Fe alloys have been considered to be potentially important for applications at high temperature by reason of their low density end expected high specific strength.
