Abstract
In this study, a novel extrusion-shear (ES) deformation method was developed to prepare ZC61 alloy. The dynamic mechanical properties and microstructure of specimen were studied at a temperature in the range of 25–350°C and strain rate of 1300 s−1. The results demonstrated by ES exhibited a strong {0001} basal texture, resulting in the obvious anisotropy. The shapes of stress–strain curves of samples exhibited significant differences at low temperature (<250 °C) when compression was carried out along extrusion direction (ED) and extrusion radial direction (ERD). Dynamic recrystallization occurred at the loading temperature of 300°C along ED due to the energy provided by high-density dislocation in twins. However, no obvious dynamic recrystallization was observed for the ERD samples.
