Morphological and Mechanical Behaviour of Cu–Sn Alloys—A review

The current paper reviews the research conducted on wrought Cu–Sn, Cu–Sn–Ti and Cu–Sn–Zn alloys intending to reveal the details on morphological and mechanical behaviour during various manufacturing operations. The motivational force of employing copper-based alloys in automotive and marine industries is its mechanical properties and corrosion resistance. One of the important factors that affect mechanical properties is micrograph. The grain size, grain distribution, heat treatment, morphological behaviour and the intermediate phase formation highly influence the properties of the copper-based alloys. Moreover, the change in microstructure through different manufacturing process (wrought process), heat treatment and addition of alloying element also improve the mechanical and thermal properties. This paper aims to review the major conclusions on improving the microstructure and mechanical behaviour of wrought Cu–Sn, Cu–Sn–Zn and Cu–Sn–Ti alloys. Analysis and observations of each investigation were prepared by incorporating the morphological results obtained through Optical Microscope, Transmission Electron Microscope, Scanning Electron Microscope, X-ray Diffraction Technique and Electron Dispersive Spectroscopy. This review paper also attempts to give the areas of future researches and developments that can be made for these wrought alloys.
