Mechanical Strength and Failure Characteristics of Cast Mg-9 pctAl-1 pctZn Alloys Produced by a Heated-Mold Continuous Casting Process: Tensile Properties
Abstract:MITSUHIRO OKAYASU, SHUHEI TAKEUCHI, and HIROAKI OHFUJIThe mechanical properties and failure characteristics of a cast Mg alloy (AZ91: Mg-Al 8.9 -Zn 0.6 -Mn 0.2 ) produced by a heated-mold continuous casting process (HMC) are investigated. In a modification of the original HMC process, the cooling of the liquid alloy by direct water spray is carried out in an atmosphere of high-purity argon gas. The HMC-AZ91 alloy exhibits excellent mechanical properties (high strength and high ductility) that are about twice a… Show more
