Hypereutectic pistons and turbos?
Thanks for the info guys. For what its worth, the problem isn't with finding forged pistons, but with finding "machine to fit" forged pistons. The bore and pin diameter for the 305 is correct for my application, but these are actually going into a 2.3L mercedes/cosworth engine.

#3---- Hypereutectic or Forged?
Hypereutectic 390 refers to a unique aluminum piston alloy that contains dissolved and free silicon. The material can be T6 heat treated to high strength and stiffness. Non-heat treated 390 hypereutectic alloy aluminum has slightly less strength than conventionally cast F-132 aluminum.

When is a Cast Iron Eutectic? | International Journal of
The literature often mentions that cast irons that appear eutectic by thermal analysis are hypereutectic if one refers to the equilibrium phase diagram. This is a source of ambiguity and confusion. The analysis of experimental results on hypereutectic cast irons has previously shown that taking into account the solidification path during the primary precipitation …

Hypereutectoid Alloy
However, hypereutectic reactions have a smaller concentration of solid solution of one metal and a greater concentration of the other secondary metal in comparison to the parent eutectic mixture. Therefore, a reduction in the system temperature will result in the precipitation of one component of the mixture. In industrial applications, the ...

Hypereutectoid Steel
Through-hardened steels like AISI 52100 are hypereutectic alloys, where the carbon content is greater than 0.77% C by weight. Fig. 3.11 shows a representation of the Fe-C phase diagram along with schematic illustrations of the probable microstructures realized by slowly cooling a hypereutectic Fe-1% C alloy and a hypoeutectic Fe-0.6% alloy. The phases shown in this …

Revisiting Thermal Analysis of Hypereutectic Spheroidal …
This study deals with early solidification of hypereutectic cast irons at varying carbon content and roughly constant alloying additions. Thermal analysis of such alloys shows that the start of the eutectic reaction occurs at a nearly constant temperature for mildly hypereutectic compositions. A similar trend is observed with more hypereutectic compositions but at a higher starting …

hypereutectic piston clearence??
There are Hypereutectic pistons that need large top ring gaps (KB'S) and there are Hypereutectic pistons that do NOT need any larger gap than stock. There are Hypereutectic pistons that run very tight bore clearances, and others that can be run loose. Same goes with Forged pistons. There are some that run as tight as .0015" clearance, and ...
