AI Technical Summary
The lack of existing technology for determining the minimum castable wall thickness of magnesium-lithium alloy sand castings affects the design of the casting structure and the determination of casting process parameters.
A test method is provided for determining the minimum castable wall thickness of magnesium-lithium alloy sand castings, including designing the sample structure and dimensions, gating system, mold structure and dimensions, casting process and data evaluation principles. The minimum castable wall thickness is determined by evaluating the edges and lengths of the sample casting.
It provides clear parameter basis for the design of magnesium-lithium alloy castings and casting process design, can guide the determination of minimum wall thickness of castings of different sizes and structures, is applicable to conventional production conditions, and simplifies the process of determining the minimum castable wall thickness.
