摘要：
Experiments were conducted on commercial purity titanium to evaluate the microstructure and mechanical properties after processing by equal-channel angular pressing (ECAP) at room temperature. Samples were successfully processed through 1 and 2 passes at two different pressing speeds using an ECAP die with a channel angle of 135 degrees. Following ECAP, a microstructural evaluation showed evidence for the occurrence of basal, prismatic and pyramidal slip together with {1 0 (1) over bar 2}<(1) over bar 0 1 1 > twinning. Hardness measurements confirmed the occurrence of homogeneous strengthening throughout the samples. Tensile testing revealed a high ultimate tensile strength of similar to 750 MPa after 2 passes of ECAP but with a reduction in the measured elongation to failure. (C) 2011 Elsevier B.V.
