摘要： An aluminum silicon die cast alloy having a very low iron content and relatively high strontium content that prevents soldering to dies into die casting process. The alloys of the present invention also have a modified eutectic silicon and modified iron morphology, when iron is present, resulting in low microporosity and high impact properties. The alloy comprises 6-22% by weight silicon, 0.05 to 0.20% by weight strontium and the balance aluminum. Preferably, the alloy of the present invention contains in weight percent: 6-20% silicon, 0.05-0.10% strontium, 0.40% maximum iron and most preferably 0.20% maximum iron, 4.5% maximum copper, 0.50% maximum manganese, 0.60% maximum magnesium, 3.0% maximum zinc, balance aluminum. On cooling from the solution temperature, the strontium serves to modify the eutectic silicon structure as well as create an iron phase morphology change if iron is present, facilitating feeding through the aluminum interdendritic matrix. This, in turn, creates a finished die cast product with extremely low levels of microporosity defects. The strontium content also appears to create a non-wetting monolayer of strontium atoms on the surface of a molten casting, preventing die soldering, even at very low iron contents. The alloy may be used to cast any type of object and is particularly suited for casting outboard marine propellers, driveshaft housings, gear case housings, Gimbel rings and engine blocks.

摘要： An investment cast stainless steel article, such as a marine propeller, is composed of a stainless steel alloy containing from 14.5 to 15.2% chromium, 5.35% to 6.05% nickel and 1.0% to 1.5% silicon. During the investment casting procedure, the increased silicon in the stainless steel lowers the driving force for the silicon from reacting with the molten metal, thereby reducing casting defects and decreasing the time and labor required for final grinding and polishing of the propeller

摘要： An aluminum-silicon lost foam casting alloy having reduced microporosity and a method for casting the same is herein disclosed. A preferred lost foam cast alloy consists essentially of 6 to 12% by weight silicon and preferably 9.0 to 9.5% by weight silicon, 0.035-0.30% strontium, 0.40% maximum iron, 0.45% maximum copper, 0.49% maximum manganese, 0.60% maximum magnesium, 3.0% maximum zinc, and the balance aluminum. Most preferably, the lost foam alloy is free from iron, titanium and boron. However, such elements may exist at trace levels. Most preferably, the alloy is lost foam cast with the process that applies at least 10 atmospheres of pressure during solidification. However, the range may be 5 to 60 atmospheres. The strontium addition is greater than 0.005% by weight and most preferably greater than 0.05% by weight. In accordance with the present disclosure, alloys having substantially decreased tensile liquid failure defects and substantially decreased surface puncture defects in comparison to conventional lost foam cast aluminum silicon alloys are obtained. Further, hydrogen porosity formation is substantially completely suppressed and surface porosity defects are substantially decreased in comparison to conventional lost foam silicon alloys when casting lost foam cast alloys in accordance with the claims of the instant disclosure. The instant disclosure further discloses aluminum silicon alloys that may be utilized in both the lost foam with pressure and the die casting processes.

摘要： A hypoeutectic aluminum silicon casting alloy having a refined primary silicon particle size and a modified iron morphology. The alloy includes 10 to 11.5% by weight silicon, 0.10 to 0.70% by weight magnesium and also contains 0.05 to 0.07% by weight strontium. On cooling from the solution temperature, the strontium serves to modify the silicon eutectic structure as well as create an iron phase morphology change. Such changes facilitate feeding through the aluminum interdendritic matrix. This, in turn, creates a finished die cast product with extremely low levels of microporosity defects. The alloy may be used to cast engine blocks for marine outboard and stern drive motors. Furthermore, when the magnesium levels are adjusted to approximately 0.10 to 0.20% by weight magnesium, propellers having a highly advantageous ductility may be obtained.

摘要： An environmentally friendly, formaldehyde-free, aqueous binder composition that includes a carbohydrate, a crosslinking agent, and a pre-reacted product of an alcohol or polyol and monomeric or polymeric polycarboxylic acid or polyglycerol is provided. The pre-reacted product may include glycerol and esters of citric acid such a monoglyceryl citrate, diglyceryl citrate, and triglyceryl citrate as well as other higher molecular weight citric acid-based esters. The inclusion of the pre-reacted product in the binder composition helps to speed the crosslinking reaction, induces faster water evaporation, decreases the viscosity of the binder, helps to reduce the amount of water needed for application of the binder, decreases tackiness, and helps to achieve a maximum vertical expansion of the insulation pack in the transfer zone. The binder composition may be used in the formation of insulation materials and non-woven chopped strand mats.
