【 摘 要 】

In this paper we present the preliminary results of morphological analysis of Fe59Mn36.5Al3.10C3.56Cu0.237%Wt alloy. This alloy was prepared by mechanical alloying with various milling times, then hot compacted at various pressures and finally underwent presented a sintering process. The samples were characterized structurally by experimental techniques such as: X-ray diffraction and scanning electron microscopy. Each micrograph was analysed by fractal dimension using the Box Counting method in 2D; this type of tool allows you to assign a numerical value to the region which has been applied the technic. This numerical value is associated with the properties obtained by experimental techniques such as microhardness.
