Effect of Extrusion Temperature on Microstructure and Biodegradation Behavior of Mg-5Zn-1Y-1Ca Alloy

H. Jafari and F. Doost Mohammadi
Abstract—In this years, many researches on the biodegradable behavior of Mg and its alloys has been done. Low corrosion resistance of the magnesium alloys has led to search a new generation of magnesium alloys for better strength, ductility, and high corrosion resistance. In this study, Mg-5Zn-1Y-1Ca alloy was fabricated by melting process and hot extrusion (at 300, 330 and 370 °C). The effect of temperature of extrusion on microstructure and degradation behavior of Mg-5Zn-1Y-1Ca alloy were investigated by optical microscopy, scanning electron microscopy with an energy dispersive X-ray spectroscopy, X-ray diffraction, immersion test and electrochemical test. The results showed that Mg-Zn-Y-Ca alloy was composed of α-Mg, Mg3YZn6 phase and Ca2Mg6Zn3 particles. Immersion and electrochemical tests showed that extruded Mg-5Zn-1Y-1Ca alloy at 330 °C exhibited the best degradation resistance from other alloys in this study.

Index Terms—Magnesium alloys, extrusion, microstructure, biodegradable, degradation.
