摘　　要：对CuCo_2Be合金魏氏组织的形成条件、组织形态和机械性能的研究表明:CuCo_2Be合金固溶体魏氏组织在一定条件下以针状CoBe相析出,并与基体α-cu保持(100)_(CoBc)∥(200)_(α-Cu)[001]_(CoBc)∥[011]_(α-Cu)的位向关系。若将其高温退火,针状CoBe相发生球化和粗化,使合金强度,硬度下降,延伸率提高。The formation conditions morphology and machanical properties of the CuCo_2Be alloy of widmanstatten structure were studied in this paper. The results show that the widrmanstatten structure in the form of needle CoBe phase in CuCO_2Be alloy under a given condition and has a strict orientation with the matrix. The widmanstatten structure, the needle CoBe phase in CuCo_2Be alloy would be spheroidized and coarsenned, annealing for long time at high temperature after resulting in the change of mechanical properties.
