Polycrystalline hypoeutectoid aluminum bronze was fabricated by melting of pure
metals technique in an induction furnace. Cu-Al-Ni alloy was investigated in cast state and after hot extrusion. Moreover, thermomechanical treatments was conducted via torsion tests between room temperature and 9000C. The research focused to investigate the factors influencing the deformation behaviour, mechanical properties and microstructural evolution of a Cu-Al-Ni alloy. Mechanical characterization showed that upon extrusion and torsion, the alloy have increasing mechanical properties. By surveying this deformation behaviour, we point out how the current knowledgebase can pave the way for expanding utilization this aluminum bronze, attractive as structural parts in many industrial applications. The microstructure characterization of this cooper based alloy was performed by scanning electron microscopy (SEM), optical microscopy (OM) and X-ray diffractometer (XRD). The variation of the torsion moment with true strain at different temperatures was correlated with the microstructure and microhardness change. Microstructural characterization, revealed that torsion process exhibited at different temperatures have a strong effect on the grain size, which can be taken as an advantage for applications. |
