Purpose: In paper the problem concerning inoculation of pure aluminum primary structure, which is realized by introducing into metal bath of specified substances, called inoculants is presented. Design/methodology/approach: In paper the influence of different inoculants introduced to metal bath in form of master alloy sort AlTi5, AlB3, AlTi5B1, AlTi5B3 and AlTi3C0.15 on refinement of primary structure of pure aluminum is presented. The degree of structure refinement was represented by equiaxed crystals zone content on transverse section of ingot and average area of macro-grain in this zone. Findings: The results of studies and their analysis show that the most effective refinement of pure aluminum primary structure is obtained with use of master alloy sort AlTi5B1. Research limitations/implications In further research, authors of this paper are going to apply this inoculation of pure aluminum in continuous casting technology. Practical implications: The work presents refinement of structure method which is particularly important in continuous and semi - continuous casting where products are used for plastic forming. Originality/value The value of this paper resides in review of refinement effectiveness of different inoculants.
