摘要： PROBLEM TO BE SOLVED: To impart a hollow structure to the inside of metal by solving a problem that, in a conventional manufacturing method of a metal material having the hollow structure, there have been employed a casting method using a viscosity increaser and a foaming core material at melting work, and a powder method for molding by mixing a polymer material into metal powder, however, there arises such a problem that the control of a cell form becomes impossible, a magnitude of a hollow is at a level of a millimeter order, and the production of the metal powder is difficult and is in danger.SOLUTION: The metal material or the metal powder having the hollow structure is generated by: amalgamating and dispersing the particle having the hollow structure into the metal in a melted state; and then solidifying the particle.

摘要： PROBLEM TO BE SOLVED: To solve the problem that although a casting method using a thickening material and a foam core material at the time of melting or a powder method mixing and molding a metal powder with a polymeric material are used as conventional methods for manufacturing a metal material having a hollow structure, control of cell morphology is impossible, the size of a void is milli order, and manufacturing of a metal powder is difficult and dangerous, to impart a hollow structure inside metal.SOLUTION: By adding particles having a hollow structure into a metal in a molten state at a suitable ratio, forming secondary particles having the hollow particles adhered around a metal particle by mixing, and adding the secondary particles to the molten metal at a suitable ratio and solidifying the resultant mixture by additional mixing, a metal material of which the cross section has an annular or dendritic hollow structure is formed.
