| Abstract: | The ideal globular primary phase structure was first time obtained by isothermally treating the ZA12 conventional ingots with adding certain trace elements at the semi-solid state. The effects of isothermal temperature and isothermal time on the evolution of primary phase morphology were systematically investigated. The distribution of elements Zn and Al in the structure as well as the changes of eutectoid morphology inside the primary phase were also measured and analysed. |
