摘　　要：通过试验系统地研究了LD7铝合金的单级和两级时效工艺、结果表明，与传统的单级时效相比，两级时效在不降低室温强度、硬度的前提下，可显著提高合金的电导率及高温性能。With adequate experimental datum this paper deais more systematically with the single - stage anddouble - staye ageing technolosies uf LD7 alminium al1oy. The results show that .he proper double- stage technologycan obviously improvc the electric conductanc and high-temperature properties of LD7 than thc traditional single-stage ageing technology.
