Microstructures of spray formed AZ91 magnesium alloy sample were characterized in various heat treatment conditions. Different precipitation behavior of spray formed AZ91 magnesium alloy were studied at different heat treatment temperatures and hours. It is easier for the spray forming extruded allo
A novel AZ91 Ce containing magnesium alloy characterized by excellent corrosion resistance is fabricated by adding rare earth Ce (cerium) in the form of a Mg-Ce master alloy. The metallographic investigation shows that Ce added to AZ91 can obviously decrease the size of b-Mg 17 Al 12 and forms Al 11
## Abstract Two types of AZ91 magnesium alloys containing rare earth element Ce or La were fabricated. Hydrogen evolution and electrochemical tests were carried out to evaluate the corrosion behavior of new AZRE (REβ=βCe or La) and AZ91 alloys in 3.5% NaCl solutions (pH 6.50). Various corrosion rat
