This study reports the synthesis of multi-component systems by mechanical alloying, their subsequent consolidation by conventional sintering followed by mechanical and microstructural characterization. Three multi-component systems were selected and the effect of Cr, Mo and Ti is reported. Mechanical alloying leads to formation of nanocrystalline powder alloys of about 5–25 nm after 10 h of milling. XRD patterns indicate the presence of several solid solution phases with BCC and FCC structures in both the as-milled and the sintered products. After the sintering process, new equilibrium phases are crystallized from milled powder. Crystallized phases present simple structures (BCC and FCC) but with some differences in composition, besides tetragonal and/or rhombohedral structures in alloys with Cr and Mo. High hardness values are found in consolidated samples. Alloying elements, grain size, proportion and nano-size of dispersed phases have an important effect on mechanical properties.
