Abstract
The application of magnesium alloys in internal combustion engines has advantages of lightweight, better damping and noise reduction and less vibration during operation. However, the applications of magnesium pistons in internal combustion engines are still difficult due to the demanding work environment and the rigorous requirements of the increased mechanical performance, thermal conductivity, and corrosion resistance at elevated temperatures. The development of high temperature die-cast magnesium alloys for piston applications is therefore challenging, as the high temperature mechanical performance, the die casting capability, and the thermal conductivity usually conflict with each other. Here we report a die-cast magnesium alloy for the piston applications at elevated temperatures, and the alloy development and the piston manufacturing process are introduced.
