Self-Repairing Composite Alloys

It provides a composite alloy having a self-healing power. The composite alloys are provided with a matrix and a step tissue (eutectic structure). The matrix of the solid precipitate (solid precipitates) are disposed in. The solid precipitate developed a mixed sex not for the alloy forming the matrix (immiscible), and a melting point lower than alloy has a step in the tissue matrix, and has a spherical shape.
