Ignition-Proof Properties of a High-Strength Mg-Gd-Ag-Zr Alloy

A high-strength Mg-15.3Gd-l.8Ag-0.3Zr （GQ152K, mass fraction） alloy was prepared by conventional ingot metallurgy process. The solution and aging （denoted as T6） treated alloy exhibits remarkable mechanical properties with ultimate tensile strength of 421 MPa and tensile yield strength of 309 MPa. I...

Summary:A high-strength Mg-15.3Gd-l.8Ag-0.3Zr （GQ152K, mass fraction） alloy was prepared by conventional ingot metallurgy process. The solution and aging （denoted as T6） treated alloy exhibits remarkable mechanical properties with ultimate tensile strength of 421 MPa and tensile yield strength of 309 MPa. It has higher igniting temperature of 1 208 K. Moreover, it can stand against flame at 1 203 K for over 6 min in vertical burning tests, and its flammability behavior is very similar to that of 6101A1 alloy. Vertical burning tests appear to be able to directly study the flammability behavior of Mg alloys and it appears to be a good approach to study the flammability behavior of Mg alloys in an aircraft fire accident.
