Summary

Magnesium alloys has been used for a wide variety of applications, namely from the reason of their low density and high strength-to-weight ratio. Due to its attractive properties, magnesium alloys has been successfully used in various structural applications. Low inertia, which results from its low density, is advantageous in rapidly moving parts, for example automobile wheels and other automobile parts. The similar situation is in the aeronautical market and air-frame application. Trends in magnesium alloys progress for the automotive market were analyzed recently many authors [1-3]. The widely spectrum of magnesium alloy products are available with a large range of strengths and ductility. The corrosion resistance of magnesium alloys depends on many of the same factors that are critical for other metals [1,4,5]. The corrosion of magnesium alloy AZ91 after different heat treatment types (solution annealing T4 with cooling in air, water or furnace, without or with aging T6) was compared and evaluated by the test with general condensation of moisture. The relations between corrosion attack and alloy structure are also studied.
