摘　　要：采用电场凝固技术制备ZL114A铝合金,研究了电流密度和通电时间对其组织和性能的影响。结果表明:电流密度和通电时间对ZL114A铝合金的抗拉强度和伸长率有明显影响。当电流密度为57.69 mA·mm-2,通电时间为10 min时,合金的抗拉强度为345 MPa,伸长率为6.56%。Effect of current density and processing time in electric field solidification technology on microstructure and properties of ZLl14A alloy were studied. The results show that both current density and processing time have obvious influence on tensile strength and elongation of ZLl14A alloy. Tensile strength of ZLl14A alloy is 345 MPa and elongation is 6.56% when current density is 57.69 mA·mm-2and processing time is 10 min.
