MANUFACTURE OF COMPOSITE METALLIC MEMBER

Japanese Patent JP3160112

B2

PURPOSE: To improve the reinforcing effect by heating and mixing the metal where the reinforcing material is mixed in a partially solidified condition and stirring and mixing it, further heating and melting the metal in the liquid phase condition and stirring and mixing it, and again returning to the semi-molten condition and stirring it, and then, solidifying it.
CONSTITUTION: After the metal where the reinforcing material is mixed is heated and mixed in a partially solidified condition and stirred and mixed, the mixture is further heated and melted in the liquid phase condition, and the mixture is returned to the partially solidified condition again, and stirred and mixed, and then, poured in the prescribed casting mold, and solidified to obtain the casting of the prescribed shape. In addition, the metal which is pelletized by extrusion after the reinforcing material is mixed with the metal particles and the mixture is compressed is once heated and melted in a partially solidified condition and stirred and mixed, and then, heated and melted in the liquid phase condition and stirred and mixed, and again returned to the partially solidified condition, and stirred and mixed to be solidified. This constitution allows the uniform dispersion and mixture of the reinforcing material, and at the same time, and allows the mixture of the reinforcing material into the initial phase part, improving the reinforcing effect sufficiently.
