Development of Non-SF6 and Structural Control Techniques for High Performance Magnesium Alloy Project of Japan

摘要

SF6, which is used as a magnesium protection gas, is a high greenhouse effect gas whose emissions must be reduced. In Japan, in order to soive this subject, the "Development of Non-SF6 and Structural control Techniques for High Performance Magnesium Alloy Project" cooperate with four companies has been started in 2004. The aim of this project is to develop thetechnology of melting, refining and semi-continuous casting with a grain refining for a magnesiumalloy without SF6 on a mass-production scale. And the obtained magnesium alloys are used through the newiy developed metal working processes to improve the mechanical properties that are equivalent to that of aluminum alloys.
