Purpose: The goal of this work is to investigate structure and properties of powdersAl₆₇Ti₂₅Fe₈ alloys obtained by mechanical alloying. Design/methodology/approach: The powders of the Al₆₇Ti₂₅Fe₈ alloys were obtained by mechanical alloying method in a planetary Fritsh Pulverisette 5 mill. The changes of the constitution phases were tested by means of the X-ray diffractometer. The microscopic observation of the shape and size of the powdered material particles was carried out by the scanning electron microscope. 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 shows that, by using the mechanical alloying method, one can produce powder of Al₆₇Ti₂₅Fe₈ alloys with intentional chemical constitution and desirable structure. Neither impurities nor undesirable phases were observed inside the milled materials. Research limitations/implications: Using refinement of grains and phase modification it is possible to improve properties of Al₆₇Ti₂₅Fe₈ alloy. All of the presented experiments in this article are made on a laboratory scale. It is intended to develop this laboratory scale technology of production materials with better properties then traditionally cast materials in order to bring it into full production in industry. Originality/value: In addition a good microstructural homogeneity end 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 owing to their low density end expected high specific strength.
