可溶性镁合金的制备及其性能
Preparation and properties of soluble magnesium alloys
摘要
Abstract
Based on the shortcomings of the traditional fracturing ball, the soluble magnesium alloy with excellent properties was prepared by casting. This study investigated the effects of aluminum elements content on the microstructure, solubility, and mechanical properties. The results reveal that the microstructure of soluble magnesium alloy comprises the following two phases:α-Mg andβ-Mg17 Al12 . β-Mg17 Al12 increases with an increase in aluminum content and continuously distributes in theα-Mg grain boundary. In addition,α-Mg becomes coarse. The soluble magnesium alloy could dissolve in the KCl solution, and the dissolution rate increases with an in-crease in KCl concentration until the rate reaches a maximum at 3％ ( mass fraction) KCl;the rate subsequently decreases after reac-hing this maximum. In addition, the dissolution rate increases with an increase in aluminum content until the dissolution rate reaches 7. 42 mg·h-1·cm-2 . The corrosion product of the soluble magnesium alloy is finer, and the median grain size is 38. 691μm, which en-sures a smooth discharge of products, and the corrosion products are Mg17 Al12 and Mg( OH) 2 . The compressive strength of the soluble magnesium alloy could reach 430 MPa and the material breaks when the deformation reaches 3. 0％, which the plasticity of this material reduces with increased aluminum content.关键词
