The present invention is a method for producing functionally graded materials that contain a hard phase that is embedded in a metal matrix phase. The material have a continuous gradient of a matrix metal phase. An example of these types of materials include functionally graded cemented tungsten carbide (the hard phase) that has a continuous gradient of cobalt (the matrix metal) from one reference position, for example, one surface of a part, to another reference position, for example, the opposite surface of the part or within the part. The functionally graded materials are sintered via a liquid phase sintering (LPS) technique. In order to achieve the desired continuous gradient of the matrix metal, an initial gradient of one of the chemical elements of the hard phase is designed and built into the part prior to liquid phase sintering. The exact gradient of the composition material elements that will be required depends on factors such as the desired final matrix metal gradient, the dimension of the part to be made, and the sintering time and temperature.
