The obtained results show diversified mechanical properties of formed brackets forgings in the whole volume
of material. In the rib area tensile strength and hardness are considerably larger than in comparison
with the rest of the semi-finished product and initial material. This results from the specificity of the assumed
schema of the process, which considers intensive deformation in the initial material central part, which results
in forming of rib in the space between side tools. The best plastic properties are to be found in the forgings area
which underwent large strains in the areas 1 and 2, for which elongation A5 assumes values within the scope
13÷16 %. Large plasticity in these areas is caused by fine-grained, in large part recrystallized structure. The area
which underwent small strains-area 3 shows elongation A5 equal 11÷12 % at the initial material level.
It should be mentioned that a phenomena typical in forging processes is homogeneous distribution of strain
parameters in the forging. Obtaining good mechanical properties of products is strictly depended on the forging
parameters choice (temperature, strain rate, strain values), which, for the analyzed forging process of bracket from
AZ31 alloy, was made basing on results of plastometric research on analyzed alloy, conducted FEM simulations and
initial experiments.
