ABSTRACT:
A high-strength component of complex geometric shape is formed by a core of hollow spheres of metallic particles surrounded by a shell of homogeneous metallic material. The hollow spheres are intimately bonded to each other and to the inner walls of the surrounding shell by hot isostatic pressing. The pressing procedure is enhanced by the use of elements such as boron which lower the melting point of the hollow spheres, for example, when said spheres are coated by said boron.
