摘要： A method and apparatus for preparing a continuous flow of castable composite materials of nonmetallic particles in a metallic matrix, wherein particles are mixed into a molten metallic alloy to wet the molten metal to the particles, and the particles and metal are sheared past each other to promote wetting of the particles by the metal. The mixing occurs while minimizing the introduction of gas into the mixture, and while minimizing the retention of gas at the particle-liquid interface. Mixing is done at or below a maximum temperature whereat the particles do not substantially chemically degrade in the molten metal during the time required for processing, and casting is done at a temperature sufficiently high that there is no solid metal present in the melt.

摘要： A cast composite material is made from particles and a matrix alloy preselected composition that is difficult to wet to the particles. A wetting alloy having a composition that readily wets the particles is first mixed with the particles under conditions that wet the wetting alloy to the particles. The wetting alloy is selected so that it has no alloying elements in excess of that in the preselected matrix alloy, and preferably with wettability inhibiting elements reduced. After wetting and mixing have been achieved, the remaining alloying ingredients are added to the melt to adjust the matrix to the desired composition. The approach is applicable to cast composite materials containing both reactive and nonreactive particles. Also described is a cast composite material formed from about 5 to about 35 volume percent of particulate reinforcement, e.g. silicon carbide, embedded in an aluminum alloy matrix having from about 8.5 to about 12.6 weight percent silicon. This silicon-containing composite material is particularly well suited for use as a foundry alloy for remelting purposes.
摘要翻译：铸造复合材料由颗粒和基体合金预选组合物制成，难以对颗粒进行润湿。首先将具有容易润湿颗粒的组合物的润湿合金与颗粒在将润湿合金润湿颗粒的条件下混合。选择润湿合金，使得其不具有超过预选基体合金中的合金元素，优选减少润湿性抑制元素。在润湿和混合已经实现之后，将剩余的合金成分加入到熔体中以将基质调整到所需的组成。该方法适用于含有反应性和非反应性颗粒的铸造复合材料。还描述了由约5至约35体积％的颗粒增强材料形成的铸塑复合材料，例如。碳化硅，其嵌入具有约8.5至约12.6重量％硅的铝合金基体中。这种含硅复合材料特别适合用作重熔目的的铸造合金。

摘要： A composite material mixture (141) of free flowing reinforcement particles in a molten metal is solidified at a cooling rate greater than about 15 °C per second between the liquidus and solidus temperatures of the matrix alloy. This high cooling rate imparts a homogeneous structure to the solid composite material. Care is taken to avoid the introduction of gas bubbles (146) into the molten composite material while the mixture is stirred to prevent segregation of the particles. For viscous melts, an artificial surface layer such as a fiberglass blanket may be used to prevent entrapment of bubbles during precasting stirring. Additionally, gas bubbles are removed from the molten mixture by filtering (151) and skimming.

摘要： A cast composite material is prepared from a modified aluminum-containing matrix and reinforcement particles mixed into the matrix. From about 15 to about 130, preferably from about 20 to about 50, parts per million of an element, preferably beryllium, that forms a more stable oxide than magnesium oxide is included in the matrix alloy. The stable-oxide-forming element reduces the amount and thickness of the aluminum oxide and other oxides formed at the surface of the melt, which otherwise may be mixed into the melt to cause microstructural irregularities in the matrix of the cast composite material.

摘要： A cast composite material having little spinel therein is formed from a mixture having a composition of from about 5 to about 35 volume percent of aluminum oxide reinforcing particles and from about 95 to about 65 volume percent of a molten matrix alloy. The matrix alloy is an aluminum-based alloy containing from about 0.15 to about 3 weight percent magnesium and a sufficient amount of strontium to reduce or entirely suppress spinel formation. The strontium content is from about 0.1 to about 2 weight percent of the matrix alloy. This composition is mixed to wet the matrix alloy to the particles and to distribute the particles throughout the volume of the molten matrix, while minimizing the introduction of gas into and retention of gas within the mixture. The wetted mixture is cast into molds or forms.

摘要： Un matériau composite coulé contenant peu de spinelles est formé à partir d'un mélange ayant une composition d'environ 5 à environ 35 pourcents en volume de particules de renforcement d'oxyde d'aluminium et d'environ 95 à environ 65 poucents en volume d'un alliage de matrice fondu. L'alliage de matrice est un alliage à base d'aluminium contenant environ 0,15 à environ 3 pourcents en poids de magnésium et une quantité suffisante de strontium pour diminuer ou supprimer entièrement la formation de spinelles. Le contenu en strontium est d'environ 0,1 à environ 2 pourcents en poids de l'alliage de matrice. Cette composition est mélangée pour amalgamer l'alliage de matrice avec les particules et pour distribuer les particules à travers le volume de matrice fondue, tout en minimisant l'introduction et la retention de gaz dans le mélange. Le mélange amalgamé est coulé dans des moules ou des formes.

摘要： Matériau composite coulé produit à partir de particules et d'une composition présélectionnée d'alliage matriciel qui humidifie difficilement les particules. On mélange tout d'abord les particules avec un alliage mouillant dont la composition permet de mouiller rapidement les particules, dans des conditions qui font que l'alliage mouillant humidifie lesdites particules. L'alliage mouillant est choisi de telle sorte qu'il n'ait pas d'éléments d'alliage en plus de ceux présents dans l'alliage matriciel présélectionné, et de sorte qu'il ait, de préférence, une teneur en éléments inhibant la mouillabilité. Après avoir été mouillés et mélangés, les ingrédients d'alliage restants sont ajoutés à la masse en fusion pour donner à la matrice la composition désirée. Ce procédé peut s'appliquer à des matériaux composites coulés renfermant des particules réactives ainsi que des particules non-réactives. L'invention concerne également un matériau composite coulé formé avec environ 5 à environ 35 % en volume d'un matériau de renforcement particulaire, par exemple du carbure de silicium, noyé dans une matrice d'alliage d'aluminium ayant environ de 8,5 à environ 12,6% en poids de silicium. Ce matériau composite contenant du silicium est tout particulièrement adapté pour être utilisé en tant qu'alliage de fonderie à des fins de refonte.

摘要： On décrit un appareil permettant de préparer un flux continu de matières composites coulables de particules non métalliques contenus dans une matrice métallique, lesdites particules étant mélangées pour former un alliage métallique fondu pouvant lier le métal fondu aux particules, et les particules et le métal étant mis en contact de cisaillement pour faciliter le mouillage des particules par le métal. Le mélange est réalisé en limitant la quantité de gaz pénétrant dans le mélange, et en réduisant la quantité de gaz retenu à l'interface particules/liquide. Le mélange peut avoir lieu jusqu'à une température maximale à laquelle les particules ne subissent pas de dégradation chimique dans le métal en fusion pendant le temps requis pour le traitement, et la coulée est réalisée à une température suffisamment élevée pour que le bain ne contienne aucun métal à l'état solide.
