dc.description.abstractIn view of the changes occurring in the global production plan and the imposition by the business on the market for metal products and parts, there is a tendency to replace basic parts and castings made of cast iron and steel with those made of non-ferrous metals and alloys. Some of the most used metals are copper and aluminium, and their alloys. These alloys are alloyed or modified to produce alloys with better casting, performance and corrosion properties. Aluminium bronzes are of scientific interest because they are of industrial importance at a content of 6-12 % Al with or without the addition of other elements, crystallizing in a narrow temperature range, which determines a good thinness and a high tendency to form concentrated suctions, and alloys with a content of 9-15 % Al, where the mechanical strength and hardness increase with increasing aluminium content, but their ductility and impact toughness decrease. The development aims to increase the hardness, preserve or finesse the structure and change the grain shape of aluminium bronzes by adding a small amount of B, Zr and Ti as modifiers so that the resulting castings and parts of CuAl9Fe3B, CuAl9Fe3Zr and CuAl9Fe3Ti alloys in the cast state possess high technological, corrosion and service properties.
