Structure and mechanical properties of commercial purity titanium processed by ECAP at room temperature
Structure and mechanical properties of commercial purity titanium processed by ECAP at room temperature
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?. Following ECAP, a microstructural evaluation showed evidence for the occurrence of basal, prismatic and pyramidal slip together with {1 0¯1 2}? ¯10 1 1?twinning. Hardness measurements confirmed the occurrence of homogeneous strengthening throughout the samples. Tensile testing revealed a high ultimate tensile strength of ?750 MPa after 2 passes of ECAP but with a reduction in the measured elongation to failure.

Abstract
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?. Following ECAP, a microstructural evaluation showed evidence for the occurrence of basal, prismatic and pyramidal slip together with {1 0¯1 2}? ¯10 1 1?twinning. Hardness measurements confirmed the occurrence of homogeneous strengthening throughout the samples. Tensile testing revealed a high ultimate tensile strength of ?750 MPa after 2 passes of ECAP but with a reduction in the measured elongation to failure.
