“…These results suggest that AE42 alloy is viable for use in components such as transmission cases, the service temperature of which is limited to a maximum of 150uC, but it is not recommended for use in engine blocks that are subjected to higher temperatures. 16 Recently, similar results on the bolt-load retention behaviour of AE42 alloy have been reported by researchers at the University of Michigan and Ford 26,32 and Norsk Hydro. 33…”

Creep resistance is a major requirement for the use of magnesium in automotive powertrain components that are currently made of aluminium or cast iron. This paper summarises various new magnesium alloys that have been developed in recent years for elevated temperature applications. The alloy development basis, mechanical properties, creep resistance, bolt-load retention characteristics, and microstructure of seven new alloy systems (

“…Mg alloys has gained significant interests to the automobile and aerospace industries due to their low densities and adequate strength/weight ratios. [1][2][3] A significant limitation, however, is their corrosion performance. [4][5][6][7][8][9][10][11] It is important to understand the effect of processing conditions on the corrosion performance.…”

The effects of heat treatments, including T4, T5, T6 treatments, on corrosion behaviors of Mg-7Al-2Sn (AT72) alloy processed by high vacuum die casting have been investigated. The optical microscope, scanning electron microscope observations were used to analyze the microstructures, especially the distribution of second phase, phase contents and grain size. The hydrogen evolution tests, electrochemical methods including open circuit potential curves and polarization curves were used to describe the corrosion properties as well. The results indicated that different heat treatments had influence on microstructures, especially distribution of second phase, phase contents and grain sizes. The existence of second phase had a relationship with corrosion properties, in which the as-cast samples showed low corrosion rate in hydrogen evolution tests while the heat treatment methods had little impact on improving corrosion resistance. The electrochemical analyses also agreed with this observation. Based on these results, the optimized heat treatment method for corrosion resistant AT72 magnesium alloy has been established.
