Densification and microstructure of cross-roll rolled Cu–15% In powder using copper can

Abstract: This work describes the role of temperature and rolling method on density and microstructure changes in Cu–15% In (wt%) alloy powder during normal and cross-roll rolling. The rolled specimen consisted of two distinct microstructures: α-Cu and Cu7In3 intermetallic compounds. The specimen obtained with 5° of cross rolling degree and 60% of rolling reduction ratio at 600°C has the highest density of 8.812g/cm3. A detailed analysis of these results in terms of the microstructural changes and densification mechanisms is also presented. [Copyright &y& Elsevier]
