ABSTRACT
In this paper, mainly through collection of magnesium alloy and other related alloys to study the nature of strontium magnesium alloy forming properties. Strontium mainly on the magnesium alloy performance liquid molding, plastic molding and welding of the performance. Liquid molding on the main performance liquid filling capability, mobility, impact on liquid molding liquid and a major factor shaping the characteristics and changes in liquid molding of the main channels. Plastic molding focuses on the general approach was characterized as elongation, the shrinkage rate and the extent and impact of liquid compression molding methods and ways to improve the liquid molding. Molding and forming characteristics is that the combination of methods. Welding of the major expositions of the strontium-magnesium alloy can be welded, as well as its impact on weldability of factors, such as the line energy, the fusion ratio, the welding is also forming the characteristics of various methods of welding. Strontium on the magnesium alloy forming the special performance, the main method of forming special elaborate. Finally, there is molding of magnesium alloy strontium on the prospects of strontium and magnesium alloy on the field of application.
The results show that: magnesium alloy liquid molding of strontium include filling capacity and mobility, characterized as easy to oxidation, the casting process of adaptability. Strontium improved magnesium alloy liquid molding of the main ways that reduce impurities in the alloy content, as well as external conditions improve pouring and mixing, such as magnetic field oscillations. Strontium liquid magnesium alloy plastic molding properties include elongation, area reduction rate, compression ratio. Forming the main characteristics of low temperature for molding, molding process demanding. Ways to improve and enhance the organization and composition uniformity and improve the uniformity of deformation and distortion temperature control. Strontium magnesium alloy welding forming properties including strontium magnesium alloy weldability.
