%X The influence of deformation degree on intergranular corrosion of hot rolled plate of 2519 aluminum alloy was studied by chemical soak experiment and metallographic analysis. The irregurlar distribution of precipitation phase and the difference of grain shape and size have been caused by the different deformation degree under the same strain rate and deformation temperature. As a result, the intergranular corrosion rate is larger for the alloy experienced a large deformation degree than that a small deformation degree. At room temperature, experiment data demonstrate that the intergranular corrosion rate with time of 2519 alloy in 3. 5 % NaCl + 1 % HC1 solution followed an exponent function.
