Determination on the effect of Ti addition on the mechanical behavior of as-cast Cu-6Sn alloy

This research assessed the effect of Ti addition on the microstructure, hardness and tensile strength of as-cast Cu-6Sn alloy which is generally used to manufacture bearings, propellers and impellers. The alloying element was added in concentration of 1 wt% and the samples were cast using permanent die casting. Optical microscope and Energy dispersion spectroscopy (EDS) were used to determine the distribution of the second phase in the alloy. Vickers -hardness tester and Universal testing machine (UTM) were used in this investigation. The results indicate some influence of minor amount of Ti, the mechanical properties (Hardness, UTS, YS and %EL) of as-cast Cu-6Sn alloys were observed to improve with the addition of Ti. The improvement of mechanical properties of Cu-6Sn alloy can be attributed towards the formation of an intermediate phase due to addition of Ti. The research in these works are found to be in accordance with previous literatures.This research assessed the effect of Ti addition on the microstructure, hardness and tensile strength of as-cast Cu-6Sn alloy which is generally used to manufacture bearings, propellers and impellers.
