摘要	Severe plastic deformation (SPD) and aging treatment seriously affect the microstructure, precipitation phase distribute then seriously affect comprehensive properties of CuCrZr alloy. The microstructure, orientation, texture characteristics, and precipitated phase structure after equal channel angular pressing (ECAP) by route C deformation and aging treatment were investigated by scanning electron microscope (SEM), X-ray diffraction (XRD), electron back-scattered diffraction (EBSD) and transmission electron microscope (TEM). The results show that, after ECAP the initial equiaxial crystal gradually transformed into fibrous structure along the extrusion direction, with the increasing strain, the texture undergoes a strong undulation, continuous twinning occurs within some oriented grains, with an initial {112} copper texture that transformed to a stronger {110} Goss texture. Aging treatment can intensify discontinuity distribution of nanoscale precipitation along grain boundaries; After 4 passes and aging at 450 for 4 h the strength, hardness and conductivity reached to 577.2 MPa, 184.5Hv and 78.5%IACS, respectively, and showed a continuous increasing trend. © 2022 Elsevier Ltd
