摘　　要：通过对新时效制度（通过导电率和硬度实验初步确定的）和自然时效制度下的2024铝合金晶间腐蚀实验研究和对比分析，验证了新时效制度的2024铝合金耐腐性能已达到自然时效时的耐腐性能。Experimental reseaches into intergranular attack to aluminum alloy 2O24 are carried out under theconditions of a new type of aging process-which is determined preliminarily by tests of electricconductivity and hardness, and the natural aging process. A comparative analysis of the experimentalresults shows that the corrosion resistant performance of aluminum 2024 in the new type of aging processcan rival that in natural aging process.
