粉末锻造工艺对制备新型电池箔材用纯铝板材的组织及性能影响
Effect of Powder Forging on the Microstructure and Properties of Commercial-Purity Aluminum for a Novel Battery Foil Material
摘要
Abstract
To meet the synergistic requirements of strength,ductility,and electrical conductivity for ultrathin battery aluminum foil,a powder-forging route was employed in this study to fabricate a novel commercial-purity Al plate for battery foil applications,and the effects of ball-milling time and hot-forging temperature on its microstructure and properties were systematically investigated.The results show that high-energy ball milling can produce ultrafine-grained Al powders characterized by a high density of dislocations and stacking faults.It was further found that the hot-forging temperature strongly affects the dynamic recovery and recrystallization behavior,and the forged Al plates exhibit a typical trade-off between mechanical properties and electrical conductivity.The sample forged at 560℃showed a relatively high ultimate tensile strength of 375.9 MPa,but low elongation and electrical conductivity of 1.99%and 48.7%IACS,respectively.When the temperature increased to 600℃,the ductility and electrical conductivity improved to 4.74%and 53.2%IACS,respectively,whereas the strength decreased accordingly,with an ultimate tensile strength of 208.64 MPa.Compared with the industrially used Al plate as the rolling stock for aluminum foil,the as-prepared high-strength pure Al plate exhibited an increase in ultimate tensile strength of 90%~240%.The high strength of this material is mainly attributed to the synergistic effects of dislocation strengthening,grain-refinement strengthening,and stacking-fault strengthening.Therefore,the powder-forging route enables tunable optimization of strength,ductility,and electrical conductivity in a pure Al system without relying on complex age-hardening treatments,and provides a billet with excellent microstructural and mechanical properties for subsequent foil-rolling processes.关键词
