Abstract:
1. A method comprising: providing a first layer comprising a first powder material and a second layer comprising a second powder material over the first layer, and compacting the first powder material and the second powder material using at least a first magnetic field wherein compacting a first powder material and a second powder material using at least a first magnetic field comprises providing a first electrically conductive container and placing the first powder material in the first container and wherein the first magnetic field induces a current in the first container producing a second magnetic field so that the first and second magnetic fields repel each other and the first container is compressed to compact the first powder material to provide a first compact, and thereafter sintering at least a portion of the first compact to provide a first sintered component, and thereafter, placing the first sintered component in a second electrically conductive container and placing the second powder material in the second container and so that a third magnetic field produces a current in the second container producing a fourth magnetic field and so that the third magnetic field and the fourth magnetic fields repel each other so that the second container is compressed to compact the second powder material.
