A method comprises providing a molten aluminum alloy selected from the group consisting of 6000 series aluminum alloys comprises chromium (Cr) in a range of between 0.001 wt % to 0.05 wt %. The molten aluminum alloy is formed into a formed body having beta-AlFeSi particles. The formed body is solution heat treated at a temperature in a range of 1,025-1,050 F. to form a heat-treated body. The solution heat treating transforms substantially all of the beta-AlFeSi particles into alpha-AlFeSi particles such that the heat-treated body is substantially free of the beta-AlFeSi particles.

Provided is a metal material for 3D printing, the metal material including an alloy that includes a eutectic metal, and a metal particle, wherein the melting point of the alloy is about 100 C. to about 300 C., and the melting point of the metal particle exceeds about 300 C.

An AlSiFe-based aluminum alloy casting material that is excellent in elongation while having characteristics of high rigidity and a method for producing the same are provided. The AlSiFe-based aluminum alloy casting material has a composition that includes: Si, a content of which is 12.0% by mass or more and 25.0% by mass or less; Fe, a content of which is 0.48% by mass or more and 4.0% by mass or less; Cr, a content of which is 0.17% by mass or more and 5.0% by mass or less; and a remainder composed of Al and unavoidable impurities. The casting material includes a structure, in which a Si-based crystallized product surrounds an AlCrSi-based compound.

A method of casting an aluminum alloy is provided. The method includes casting a master aluminum alloy having a trisilanol phenyl polyhedral oligomeric silsesquioxanes (TSP) modifier into an ingot and adding the master aluminum alloy ingot into a molten base aluminum alloy to form a modified aluminum alloy. The modified aluminum alloy is heated for a period of time and then cast into a cast component. A variation of the method includes mixing a powdered aluminum alloy with a powdered TSP and pressing the mixture of powdered TSP and powdered aluminum alloy into a compacted preform prior to casting the master aluminum alloy. The compacted preform is melted during the step of casting the master aluminum alloy.

The present invention relates to a process for producing a piston made of hypereutectic AlSi alloy with a cast iron Alfin ring and a piston obtained through said process. The process according to the invention allows to obtain high adhesion of the Alfin ring to the piston body, making it particularly suitable for use in high performance engines.

The semi-solid molding method of the present invention comprises six parts as the traditional method: a mold, a main machine, an injection system, a pulping machine, a quantitative feeding system, and a holding furnace; the injection system, the pulping machine, and the quantitative feeding system are combined and called integrated pulping injection system, and the system is placed in the holding furnace. In order to adapt to the difficulty of molding the semi-solid slurry to carry less heat into the mold with large wall thickness, the semi-solid mold is divided into three layers according to the function, which greatly reduces the heat absorption capacity of the mold, due to the characteristics of the constant flow pump, the holding pressure after filling can reach 0.01 MPa-30 MPa, so low pressure casting, high pressure casting, differential pressure casting, liquid die forging and semi-solid extrusion forging can be unified in one kind of main machine.
