摘要: Abstract The current work presents the room-temperature mechanical properties and corrosion resistance in 3.5% NaCl solution of conventional casting rapidly solidified Mg6ZnMn (ZM61) magnesium alloys. It is found that ZM61 alloy are dramatically enhanced, with ultimate strength increased from 335 MPa to 460 MPa (37% increment), which can be attributed formation refined dendrite microstructure strengthening MgZn 2 phase distributed within matrix. Furthermore, performs better than extruded ZK60 pure Mg alloys, suggesting rapid-solidification technique a promising way improve for structural corrosive media utilization.
