Abstract
A titanium-based metal matrix microcomposite material. About 1% to about 25% by weight TiB.sub.2 is substantially uniformly incorporated in a titanium-based alloy matrix. The microcomposite material is formed by sintering at a temperature selected to preclude diffusion of TiB.sub.2 into the matrix. The microcomposite material may be used in a process for cladding a macrocomposite structure.
Claims2
A method of cladding a macrocomposite structure comprising:
- providing a matrix material consisting essentially of a titanium-based alloy and a microcomposite material comprised of a metal matrix consisting essentially of a titanium-based alloy, and about 1% to about 25% by weight TiB.sub.2 substantially uniformly incorporated in the matrix;
- selecting one of said matrix material and said composite material;
- pressing the selected material to form a layer;
- pressing the remaining material onto the layer of the selected material to form a multi-layered compact;
- and
- sintering the multi-layered compact to form an integral metallurgical bond between the layers of the compact with diffusion but essentially no composition gradient between the layers.
