(Working notes)

  1. Virtually any Al-containing Mg alloy consists of two main phases (the very important influence of minor additives is ignored at this stage):
    α-phase: essentially pure magnesium
    β-phase: Mg17Al12 (calculated 55.7wt% Mg)
  2. Considering the equilibrium phase diagram for the system Al...

Two postgraduates (each in the framework of his/her research) had to compare corrosion rates of magnesium alloys in salt water measured by several techniques. Both obtained weird results, which can be summarized as follows:

  1. Four techniques provided corrosion rates on the order of magnitude of 1-5...
