INVESTIGATION OF THE INFLUENCE OF MO, W AND V MODIFICATION ON THE STRUCTURE AND HARDNESS OF IRON-DOPED CuAl9 BRONZE IN THE CAST STATE

Abstract

Of the group of tin-free bronzes, the most widespread in foundry production is the use of so-called "aluminium" bronze, or bronze type CuAl₉. Double bronzes of this type tend to "self-anneal", resulting in a coarse-grained cast structure. To suppress this tendency, aluminium bronzes are most commonly alloyed with iron, manganese and nickel, but are also further modified with various modifiers. The aim of this development is to investigate the influence of Mo, W and V modification on the structure and hardness of iron alloyed CuAl₉ type in the cast state.
