摘　　要：研究了淬火时效对4032B铝合金组织和性能的影响。结果表明,4032B铝合金材料对淬火时效非常敏感,强度随时效后析出相的增多迅速增强,而塑性相应降低;所研制的4032B铝合金棒材T6态的抗拉强度、屈服强度和伸长率的平均值分别为408.70 MPa、385.92 MPa和3.9%。The influences of quenching-aging on microstructure and properties of 4032B aluminum alloy were studied. The results show that the quench sensitivity of the alloy is strong, and with the increase of the precipitate phase, the strength increases rapidly, the plastic decreases. The tensile strength, yield strength and elongation of the 4032B aluminum alloy bar aiter quenching-aging is 408.70 MPa, 385.92 MPa and 3.9%, respectively.
