Title:
【発明の名称】安定な酸化物形成元素を含有するマトリックスを有する鋳造複合材料
Document Type and Number:
Japanese Patent JP3283508
Kind Code:
B2
Abstract:
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.
