The development of high-strength flame-retardant magnesium alloys

Magnesium alloys possess a great potential for applications in the automobile and aerospace industries due to their extremely low density, exceptional machinability and enhanced dampening capacity.However, the low elastic modulus, low ductility, high flammability, and susceptibility to corrosion dramatically impeded their applications.In recent dec
