Abstract

An aluminum composite material includes a first metallic plate, a second metallic plate, and a matrix material that is interposed between the first metallic plate and the second metallic plate and is formed of aluminum powder. Gadolinium oxide particles are dispersed in the matrix material.

First claim

The invention claimed is:

1. An aluminum composite material comprising:
a first metallic plate;
a second metallic plate; and
a matrix material that is interposed between the first metallic plate and the second metallic plate and is formed of aluminum powder, wherein
the matrix material contains gadolinium oxide particles in an amount of 6% by mass or more and 15% by mass or less, and
the aluminum composite material has a percentage elongation of 12.6% or more and 20.8% or less.

2. An aluminum composite material comprising:
a first metallic plate;
a second metallic plate; and
a matrix material that is interposed between the first metallic plate and the second metallic plate and is formed of aluminum powder, wherein
the matrix material contains gadolinium oxide particles in an amount of 2% by mass or more and 20% by mass or less and contains boron carbide particles in an amount of 10% by mass or more and 20% by mass or less, and
the aluminum composite material has a 0.2% yield strength of 127 MPa or more and 139 MPa or less.

3. An aluminum composite material comprising:
a first metallic plate;
a second metallic plate; and
a matrix material that is interposed between the first metallic plate and the second metallic plate and is formed of aluminum powder, wherein
the matrix material contains gadolinium oxide particles in an amount of 2% by mass or more and 10% by mass or less and contains boron carbide particles in an amount of 10% by mass or more and 20% by mass or less, and
the aluminum composite material has a percentage elongation of 6.7% or more and 11.2% or less.
