摘要 研究应用ECAP法与热处理工艺相结合的方法改性2224铝合金的过程,对改性2224铝合金的力学性能及显微组织进行比较分析。结果表明,退火态2224铝合金经ECAP挤压后,进行固溶和时效处理,明显提高了合金的力学性能,细化了合金的晶粒。与通常的变形2224铝合金相比,改性2224铝合金更有实际应用价值。 The 2224 aluminum alloy modification process by equal channel angular pressing (ECAP)combined with heat-treatment is investigated, and the microstructure and mechanical properties of the processed 2224 aluminum alloy are analyzed and compared. It is shown that the mechanical properties of annealed sample of 2224 aluminum alloy are improved by the combination of solid solution and aging treatment after ECAP, the size of grain is refined. Compared with traditional alloy, the modified 2224 aluminum alloy has significant importance for practical application.
