Abstract
In order to find good candidate materials for degradable fracturing ball applications, Mg-Al-Zn-Cu alloys with different contents of aluminum, zinc, and copper were prepared by ingot metallurgy. The effects of aluminum, zinc, and copper additions on the microstructure, compressive strength, and rapid decomposition properties of the alloys have been investigated using scanning electron microscopy, compressive tests, and immersion tests. The results show that the addition of high contents Al (15 to 20 wt pct) in pure magnesium promotes a large number of network-like β-Mg17All2 phases, which helps produce more micro-thermocouples to accelerate the corrosion process in 3 wt pct potassium chloride (KCl) at 366 K (93 °C). Adding different Zn contents improves the compressive properties of Mg-20Al alloys drastically. However, it decreases the decomposition rate in 3 wt pct KCl at 366 K (93 °C). Small amount of Cu will slightly reduce the compressive strength of Mg-20Al-5Zn alloy but dramatically increase its decomposition rate.
