Abstract

High-strength Mg–9Al–1Cu alloy is used as a soluble plugging material for multistage fracturing, and the effect of hot extrusion on its corrosion behavior is analyzed. As-cast (AC) Mg–9Al–1Cu alloy consists of α-Mg, Mg₁₇Al₁₂, and MgAlCu phases. After hot extrusion, grains are obviously refined and average size is reduced from 90.67 to 3.75 μm, coarse Mg₁₇Al₁₂ and MgAlCu phases are broken and distributed at grain boundaries, and grain orientation changes from random state to obvious {10 $\bar{1}$ 0} texture. The corrosion forms of both AC and as-extruded Mg–9Al–1Cu alloys are mainly pitting corrosion, but hot extrusion reduces the corrosion rate attributed to the fine second phases located at the grain boundaries of recrystallized grains and the dense oxide film containing more MgAl₂O₄ compound.

热挤压对可溶Mg-9Al-1Cu合金多级断裂组织及腐蚀行为的影响

采用高强度Mg-9Al-1Cu合金作为多级压裂的可溶性封堵材料，分析了热挤压对其腐蚀行为的影响。铸态（AC） Mg-9Al-1Cu合金由α-Mg、Mg17Al12和MgAlCu相组成。热挤压后晶粒细化明显，晶粒平均尺寸从90.67 μm减小到3.75 μm，晶粒边界处Mg17Al12和MgAlCu粗相断裂分布，晶粒取向由随机状态转变为明显的{10 1¯$\bar{1}$ 0}织构。AC和挤压态Mg-9Al-1Cu合金的腐蚀形式均以点蚀为主，而热挤压态腐蚀主要是由于再结晶晶粒晶界处的细小第二相和含有较多MgAl2O4化合物的致密氧化膜降低了腐蚀速率。
