Effect of equal-channel angular pressing on the mechanical behavior of a Bi-Sn eutectic alloy
Effect of equal-channel angular pressing on the mechanical behavior of a Bi-Sn eutectic alloy
Equal-channel angular pressing (ECAP) was utilized to process a Bi‒42Sn eutectic alloy at room temperature using processing route A for 1, 2, 4, and 8 passes. Tensile testing was performed at room temperature under initial strain rates in the range of 1.0 × 10-5 to 1.0 ×10-2 s-1. The results demonstrate that processing by ECAP improves the ductility in this material and the elongations to failure increased with decreasing strain rate in all samples. The largest elongation to failure, ~1300%, was recorded in the sample processed by ECAP for 8 passes at an initial strain rate of 1.0 × 10-5 s-1. This elongation is much improved by comparison with the as-cast Bi‒42Sn alloy.

Abstract
Equal-channel angular pressing (ECAP) was utilized to process a Bi‒42Sn eutectic alloy at room temperature using processing route A for 1, 2, 4, and 8 passes. Tensile testing was performed at room temperature under initial strain rates in the range of 1.0 × 10-5 to 1.0 ×10-2 s-1. The results demonstrate that processing by ECAP improves the ductility in this material and the elongations to failure increased with decreasing strain rate in all samples. The largest elongation to failure, ~1300%, was recorded in the sample processed by ECAP for 8 passes at an initial strain rate of 1.0 × 10-5 s-1. This elongation is much improved by comparison with the as-cast Bi‒42Sn alloy.
