On selection of advanced compositions of flame resistant magnesium alloys

Magnesium alloys are among the most advanced structural materials in aviation and mechanical engineering industry due to their low density high strength-weight ratio, but ability ignite at temperatures from 500°C, while actively sustaining combustion, can cause disastrous consequences even event of minor emergencies. This paper is intended investigate compositions that enhance flame resistance magnesium alloys. Comparison was made between ignition commercial cast alloy ML10, LPSO-structure alloy, with rare earth metals, variations these different additives — agents improve resistance. It has been established maximum provided by those contain both LPSO phase Yb or Ca additive as capable raising temperature 1000°C higher.
