英文摘要	Equal-channel angular pressing (ECAP) technique has emerged as a desirable strategy to fairly improve the properties of magnesium (Mg) alloys. However, poor workability of Mg alloys results in the failure of ECAP processing. Herein, a novel differential-thermal ECAP (DTECAP) process, simultaneously endowing Mg-SnZn-Zr (TZK) alloys with good deformability and superior mechanical properties, was developed. Analysis of deformation microstructures of TZK alloys revealed that the excellent comprehensive properties were mainly associated with the activation of non-basal slip, grain refinement, and texture weakening. The results indicated that prismatic a 0001 // ND-preferred texture was weakened from 13.48 to 9.38 (m.r.d.), and exhibited ED-split components. The current study can provide beneficial insights into the development of high-performance Mg alloys via DTECAP processing. (c) 2021 Elsevier B.V. All rights reserved.
