Original abstract
In the last decade, multicomponent alloys arisen as new promising family of materials. The effect of milling parameters, namely milling balls size, milling speed and time on synthesis of inequiatomic AlCoCrFeNiTi0,5 mechanically alloyed (MA) powders in planetary ball mill were studied. Alloying behaviour, morphology, size and homogeneity of powders were observed by X-ray diffraction (XRD) and scanning electron microscopy (SEM). During MA, a supersaturated Cr based solid solution with BCC structure was formed after 24 hours of milling, with significantly reduced grain size. It was revealed, that selection of milling conditions have a great influence on milled powders properties. In general softer milling condition result in decreased particle size and homogeneity
