SPF/DB Research in ZK60 Alloy with Gasification Agent as Pressurization Mediator

Article Preview

Abstract:

A new SPF/DB technology using gasification agent as pressurization mediator was proposed in this paper. The forming principle of SPF/DB using the agent was represented. Dies used for the forming process was designed and manufactured, and new gasification agent N11 which is white solid powder at normal temperature and it is easy to encapsulate and keep was developed for magnesium alloy. ZK60 magnesium alloy with a thickness of 1mm and grain size of 7.9μm was selected to conduct the experiment of SPF/DB. Corrugated ZK60 magnesium alloy parts were well formed under the temperature between 653K and 673K and forming time of 50 minutes. SEM was used to observe the microstructures of the diffusion bonding joints. The result shows that the joints were well bonded.
