Abstract: A die cast part, such as an electric drive unit, a high pressure die casting system, and a method of forming a die cast part. The high pressure die casting system includes a shot sleeve including a pour hole, a launder connected to the pour hole, a furnace connected to the launder, a mold cavity connected to the shot sleeve by a sprue post, and a heating system including at least one proximal channel located under the pour hole under the shot sleeve. The feedstock is melted in the furnace and transferred by a launder into the preheated shot sleeve through a pour hole. The feedstock is injected into a mold cavity, wherein the temperature of the feedstock is above the solidus temperature of the feedstock upon entering the mold cavity.

Abstract: A quantitative metallographic method to measure skin layer thickness in high pressure die cast aluminum components. Because the faster-cooling skin layer region exhibits a higher volume fraction of eutectic phases than that of a slower-cooling inner region, measurements showing such higher eutectic phases can be used to quantify such layer thickness. An image at various thicknesses of a location of interest in a cast component sample is first obtained using an image analyzer, from which eutectic volume fractions within each of the received images may be determined. Comparisons of the determined volume fractions can be made against a known or predicted quantity for a particular alloy composition, and then correlated to the skin layer thickness via differences between the received or measured quantities and those of the known standard.
Abstract translation: 用于测量高压压铸铝组件中的表层厚度的定量金相法。 因为更快冷却的表皮层区域表现出比较慢冷却的内部区域更高的共晶相体积分数，所以可以使用显示这种更高共晶相的测量来量化这种层厚度。 首先使用图像分析仪获得铸件成分样品中感兴趣位置的各种厚度的图像，从而可以确定每个接收图像内的共晶体积分数。 可以针对特定合金组合物的已知或预测量对所确定的体积分数进行比较，然后通过接收或测量的量与已知标准物质之间的差异与皮肤层厚度相关。

Abstract: A method of incorporating additive domains in a rare earth magnet, a system for incorporating additive domains in a rare earth magnet, and a traction motor including a rare earth magnet. Inert gas and a plurality of coarse neodymium-iron-boron (NdFeB) particles are introduced into the chamber of a jet mill. The plurality of coarse NdFeB particles impact each other producing a plurality of refined NdFeB particles. The plurality of refined NdFeB particles also impact a target including a target material and transfer a portion of the target material onto a surface of the refined NdFeB particles. The plurality of refined NdFeB particles including the target material are separated from the plurality of coarse NdFeB particles and collected to form a rare earth magnet.

Abstract: A method of eliminating microstructure inheritance of hypereutectic aluminum-silicon alloys. The method includes heating a first amount of the Al—Si alloy to a predetermined temperature above a liquidus temperature of the Al—Si alloy to form a first amount melt; holding the first amount melt at the predetermined temperature for a predetermined amount of time; stirring the first amount melt during the predetermined amount of time; heating a second amount of the Al—Si alloy above the liquidus temperature of the Al—Si alloy to form a second amount melt; and mixing the first amount melt and the second amount melt to form a processed Al—Si casting alloy. The predetermined temperature is between about 750° C. to 850° C. The predetermined amount of time is between 0.1 hour to 0.5 hour. The processed Al—Si casting alloy contains about 30 wt % to about 40 wt % of the first amount of the Al—Si alloy.
