摘要： An article of manufacture includes a cemented carbide piece7 and a joining phase that binds the cemented carbide piece into the article. The joining phase includes inorganic particles and a matrix material. The matrix material is a metal and a metallic alloy. The melting temperature of the inorganic particles is higher than the melting temperature of the matrix material. A method includes infiltrating the space between the inorganic particles and the cemented carbide piece with a molten metal or metal alloy followed by solidification of the metal or metal alloy to form an article of manufacture.
