The investigations were introduced in the paper, method of thermal and derivative analysis (TDA), the process of crystallization and phase transformation in the solid state of the aluminium bronze CuA110Fe4Ni4 (BA1044) and with the addition 0.3 % Cr. Two intermetallic phase were identified in the microstructure of the bronze BA1044: [kappa]Fe1-- rich in Fe and Cu and [kappa]Fe2 - rich in Fe, and in the microstructure of the bronze BA1044+0.3 % Cr only one phase [kappa]Fel - rich in Fe, Cu and Cr. The presence of chrome in the bronze BA1044 reduce size the primary crystals of the phase [beta], reduces the dynamics of the processes of thermal phase transformation in the solid state and lengthens the time their of duration.
