利用多向锻造及时效处理技术加工变形铝合金,使铝合具有高强度和良好的塑性。研究结果表明,试样组织显著细化且超细的第二相微粒弥散分布,抗拉强度和硬度大幅度增加且塑性良好,抗拉强度和伸长率分别为396.3 MPa和11.08%。锻件强度和硬度大幅度提高是由于组织显著细化且超细的第二相微粒弥散分布;多次累积应变和时效处理改善晶界状态,使锻件的塑性增强。
The use of multi-direction forging and aging technology processing of deformed aluminum alloy, aluminum alloy with high strength and good plasticity. The results show that the microstructure of the microstructure is finely dispersed and the ultrafine second phase particles are dispersed and distributed. The tensile strength and hardness increase greatly and the plasticity is good. The tensile strength and elongation are 396.3 MPa and 11.08% respectively. The strength and hardness of the forging are greatly improved because the microstructure of the microstructure is refined and the fine second phase particles are dispersed and distributed. The strain and aging treatment are improved several times to improve the grain boundary state and enhance the plasticity of the forging.
