Microstructure Phase Analysis and Process Optimization of ZL205A Metal Mold Casting

Abstract

Abstract The ammunition body drive structural parts are typical components in the weaponry industry, with large size and wall thickness, the parts need to bear large loads when working, so their internal filling quality and mechanical properties have quite strict acceptance criteria. In this paper, we take an elastomeric transmission structure part made of ZL205A alloy as the research object, and use the metal type gravity casting technology for casting trial production, analyze the quality and mechanical properties of the molded parts of ZL205A alloy parts under different process parameters, optimize the casting process parameters, get the optimal combination of process parameters, and obtain large ZL205A castings with less internal quality defects and high mechanical properties. To solve the current problem of immaturity of domestic casting process technology for this ZL205A alloy large parts and promote the development of China's weapon and equipment manufacturing industry in the direction of light weight.
