Abstract
The development of magnesium (Mg) alloys capable of operating at demanding working temperatures above 200 °C and the ability of using high-pressure die casting for high-volume manufacturing are the most critical advancements required in develo** new alloys used to manufacture critical parts for internal combustion (IC) engines used in power tools. Here we introduce the development of a rare earth (RE)-based die-cast Mg alloy for elevated temperature applications in small IC engines. The developed Mg–RE-based die-cast alloy shows good ambient and high temperature strength, and it also has excellent high-temperature creep resistance. In addition, the developed RE-based die-cast Mg alloy shows good stiffness at elevated temperatures. Furthermore, the alloy exhibits good thermal conductivity at ambient and high temperatures, which is a key point normally neglected during the development of high-temperature Mg alloys.
