This paper reviews the following for magnesium (Mg) alloys: (a) fundamentals of oxidation and burning; (b) influence alloying on oxidation; (c) theoretical models improved resistance through with calcium (Ca), beryllium (Be), strontium (Sr) rare earth elements; (d) recent research beryllium-containing alloys; (e) proposed oxide reinforcement model. The alloys is closely related to protective incubation period, which mainly controlled by crack initially formed surface layer. Cracking facilitates vapor phase diffusion results in catastrophic eventual burning magnesium. According model, an layer increased mechanical strength hardness (such as (Mg,Be)O alloys) can better withstand internal tensile stress arising during process therefore delay cracking extend period. model provides guidance developing new oxidation-resistant alloys.
