Effect of cooling rate on corrosion resistance and behavior of micro-alloyed cast AZ91-Ca-Y alloy
Micro-alloying is an effective approach for improving the corrosion resistance of cast AZ91. However, the effect of micro-alloyed elements on corrosion resistance can be varied depending on the solidification rate influencing the diffusion and ...

Numerical simulation of low pressure die-casting aluminum wheel [PDF]
The FDM numerical simulation software, ViewCast system, was employed to simulate the low pressure die casting (LPDC) of an aluminum wheel. By analyzing the mold-fi lling and solidifi cation stage of the LPDC process, the distribution of liquid fraction ...

Root-Cause Analysis of a Failed LPBF Conformal Cooling Insert for Die Casting
Abstract This study investigates the failure of a 1.2709 (18Ni300) maraging steel insert used in high-pressure die-casting applications. The insert was manufactured by laser powder bed fusion technology. The component, featuring conformal cooling channels, was decommissioned due to coolant leakage. A comprehensive failure analysis was
