摘要

Here, we reported the CuCrZr alloy fabricated using laser melting deposition (LMD). The microstructures and mechanical properties of the CuCrZr alloy prepared by LMD and the casting technique have been comparatively investigated. The element distribution of the LMD samples with FCC single-phase solid solutions was found to be more relatively uniform than casting samples. Furthermore, the columnar grains continue to grow epitaxially following the heat flux direction, leading to the formation of a periodical orientation texture along the deposited directions in the LMD process. The mechanical properties of the LMD samples along the scanning direction are similar to those of the cast sample, while the yield strength along the deposition direction is more than twice as high as that of the cast samples (up to 150 MPa). The plasticity remains unchanged because the direction of the stretch is consistent with the periodical orientation texture direction.
