Abstract :
In this research, the effect of initial microstructure and solution treatment on rollability and crystallographic texture of a Cu-Mn-Ni-Sn alloy has been investigated. The initial tests indicated that the rolling of the alloy at different temperature was not possible due to formation of second phases. Therefore, to eliminate the phase segregation, proper temperature for solution treatment was selected as 750°C using DTA data. The obtained results showed that after 15-hour solution treatment at this temperature, the complete elimination of Sn, Mn, Ni, and Fe-rich phases may be achieved. Also, XRD data showed shift of peaks to higher angles indicating that the alloying elements were dissolved in the structure. Meanwhile, the intensity of the texture reduced and the dominant texture changed from Goss and Brass-texture to Copper-texture. Accordingly, the amount of maximum total reduction at the rolling process increased from 16.37 to 109.46 after solution treatment.
