摘要： A multiphase composite system is made by binding hard particles, such as TiC particles, of various sizes with a mixture of titanium powder and aluminum, nickel, and titanium in a master alloy or as elemental materials to produce a composite system that has advantageous energy absorbing characteristics. The multiple phases of this composite system include an aggregate phase of hard particles bound with a matrix phase. The matrix phase has at least two phases with varying amounts of aluminum, nickel, and titanium. The matrix phase forms a bond with the hard particles and has varying degrees of hard and ductile phases. The composite system may be used alone or bonded to other materials such as bodies of titanium or ceramic in the manufacture of ballistic armor tiles.

摘要： A method of pressure forming a brown part from metal and/or ceramic particle feedstocks includes: introducing into a mold cavity or extruder a first feedstock and one or more additional feedstocks or a green or brown state insert made from a feedstock, wherein the different feedstocks correspond to the different portions of the part; pressurizing the mold cavity or extruder to produce a preform having a plurality of portions corresponding to the first and one or more additional feedstocks, and debinding the preform. Micro voids and interstitial paths from the interior of the preform part to the exterior allow the escape of decomposing or subliming backbone component substantially without creating macro voids due to internal pressure. The large brown preform may then be sintered and subsequently thermomechanically processed to produce a net wrought microstructure and properties that are substantially free the interstitial spaces.

摘要： A method of manufacturing a weld-free apparatus for use in the connection of dissimilar metals includes the steps of providing a mold designed to replicate a reverse of the apparatus, introducing a low alloy, ferritic steel composition atomized powder into a first portion of the mold, introducing a series of atomized powders incrementally into a second portion of the mold to form a transition region between the ferritic steel composition and an austenitic stainless steel composition, and introducing an austenitic stainless steel composition atomized powder into a third portion of the mold. The method further includes the step of consolidating and melting the atomized powders in a high temperature, high pressure inert gas atmosphere to form the apparatus.

摘要： A cam member for a vehicle differential includes a cam surface made of a high-durability alloy and a clutch surface made of a high-density magnetic alloy. The cam surface and the clutch surface can either be formed into a single component or as separate components that are mechanically coupled together. In one aspect, both the high-durability alloy and the high-density magnetic alloy are powdered metal alloys. As a result, the cam member has different surfaces with optimized characteristics that would ordinarily be difficult to incorporate into a single component.
