Tensile behavior of an eutectic Pb–Sn alloy processed by ECAP and rolling

AbstractA eutectic lead–tin alloy was prepared by melting the commercially pure metals and cast in cylindrical molds with 10mm diameter. The billets were processed by 4 passes of ECAP using a die with 90° between channels through route A and rolled to a final thickness of ∼1mm. The microstructure was determined by optical microscopy. Tensile tests were carried out at room temperature in the strain rate range between 10−4 and 10−2s−1. The results show the elongation to failure increases at low strain-rates. The strain-rate sensitivity parameter was determined and a maximum value of ∼0.4 was observed at the lowest strain-rate
