摘要本论文中，采用的是工业铝板和镍箔，采用累积轧制工艺，对两种金属材料进行不同道次的复合轧制，并对轧制后的样品进行不同温度的退火，随后对已经处理完的Ni-Al复合材料进行组织和性能的观察和研究。实验通过对不同轧制道次和在同一轧制道次不同热处理温度下的试样进行维氏显微硬度计进行力学性能测试；用显微镜观察复合材料的金相组织；用万能材料试验机对其抗拉强度进行试验。62159
实验结果表明：在同一温度下通过累积轧制的次数越多，即样品轧制道次越多，Ni-Al复合板材的硬度越大，经过退火之后硬度下降。对材料的硬度来说，退火温度越高，硬度逐渐降低越低。轧制道次越多，材料的抗拉强度也就越高，反之经过退火后，轧制道次越多，材料的抗拉强度变得越差。

Abstract In this paper, the is industrial aluminum and nickel foil, the cumulative rolling process and of the two kinds of metal materials of different composite rolling, and the rolled samples were annealed at different temperature, then observes and studies on the microstructure and properties of Ni-Al composite material has been processed. Experiment through different rolling passes and in the same rolling road time different heat treatment temperatures of the specimens of Vickers microhardness tester for mechanical properties testing; with a microscope observed the microstructure of the composite. The tensile strength tests were conducted with universal material testing machine.
The experimental results show that the more the number of rolling passes at the same temperature, the more the number of rolling passes, the hardness of Ni-Al composite plate is larger, and the hardness decreases after annealing. The hardness of the material, the higher the annealing temperature, the lower the hardness gradually decreased. The more rolling pass, the higher the tensile strength of the material, and on the contrary after annealing, the more rolling passes, the tensile strength of the material becomes worse.
