Aluminium bronzes BA1032 having a multiphase microstructure, is low-deformable materials with strength close to that of high-strength steels. The influence of high-pressure torsion (HPT) and equal channel angular pressing (ECAP) on aluminium bronze structure was presented. The HPT method was found to be unsuitable for the processing of the investigated aluminium bronzes. The studies have indicated that it is possible to deform multiphase aluminium bronzes BA1032 in the ECAP process at a temperature of 400-500°C. The deformation of the bronzes at lower temperatures encounters some difficulties cracks appear which make repeated ECAP impossible.
