Deformation processing map for control of CuSi3.9 silicon bronze microstructure

The flow stress data obtained in torsion test of CuSi3.9 silicon bronze at different temperatures and strain rate are analysed using dynamic material's model which considers the workpiece as a power dissipator causing microstructural changes. A processing map representing the efficiency of power dissipation as a function of temperature and strain rate has been established and optimum processing conditions for the CuSi3.9 silicon bronze are determined.
