Development of HPDC Advanced Dies by Casting with Reinforced Tool Steels

International Journal of Manufacturing Engineering, Volume 2015, Issue 1, 2015., 2015
High pressure die casting (HPDC) dies are nowadays manufactured with high quality forged steels. Cavities are made by electrical discharge machining (EDM) or by high speed milling. The average life of an aluminium HPDC die is about 125.000 injections. Refrigeration circuits have simple configurations, because they are produced by drilling the die with ...

Refinement of primary Si in hypereutectic Al-Si alloys by intensive melt shearing [PDF]

, 2012
Hypereutectic Al-Si based alloys are gaining popularity for applications where a combination of light weight and high wear resistance is required. The high wear resistance arising from the hard primary Si particles comes at the price of extremely poor ...

Influence of Cooling Rate on Microsegregation Behavior of Magnesium Alloys

Journal of Materials, Volume 2014, Issue 1, 2014., 2014
The effect of cooling rate on microstructure and microsegregation of three commercially important magnesium alloys was investigated using Wedge (V‐shaped) castings of AZ91D, AM60B, and AE44 alloys. Thermocouples were distributed to measure the cooling rate at six different locations of the wedge casts. Solute redistribution profiles were drawn based on
