摘要： The present invention relates to a novel process for forming metal matrix composite bodies by using a barrier material. Particularly, an infiltration enhancer or an infiltration enhancer precursor or an infiltrating atmosphere are in communication with a filler material or a preform, at least at some point during the process, which permits molten matrix metal to spontaneously infiltrate the filler material or preform up to the barrier material. Such spontaneous infiltration occurs without the requirement for the application of any pressure or vacuum. Accordingly, shaped metal matrix composite bodies can be produced having superior surface finish.

摘要： A metal matrix composite is formed by contacting a molten matrix metal with a permeable mass of filler material or preform in the presence of an infiltrating atmosphere. Under these conditions, the molten matrix metal will spontaneously infiltrate the permeable mass of filler material or preform under normal atmospheric pressures. Once a desired amount of spontaneous infiltration has been achieved, or during the spontaneous infiltration step, the matrix metal which has infiltrated the permeable mass of filler material or preform is directionally solidified. The directionally solidified metal matrix composite may be heated to a temperature in excess of the liquidus temperature of the matrix metal and quenched. This technique allows the production of spontaneously infiltrated metal matrix composites having improved microstructures and properties.

Particularly, an infiltration enhancer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere are in communication with a rigidized filler material or a rigidized preform, at least at some point during the process, which permits molten matrix metal to spontaneously infiltrate the rigidized filler material or rigidized preform. Such spontaneous infiltration occurs without the requirement for the application of any pressure or vacuum. In one embodiment of the invention, a filler material or preform can be rigidized by firing and at least partially sintering the filler material so as to provide a three-dimensionally interconnected network of sintered filler material. In another embodiment of the invention, a refractory material mixture is contacted against an exterior surface of a preform or filler material and at least at some point during the process becomes structurally supportive.

摘要： The present invention relates to a novel process for forming metal matrix composite bodies. Specifically, in a particularly preferred embodiment for making metal matrix composite bodies by a spontaneous infiltration technique, an infiltration enhancer or an infiltration enhancer precursor or an infiltrating atmosphere are in communication with a rigidized filler material or a rigidized preform, at least at some point during the process, which permits molten matrix metal to spontaneously infiltrate the rigidized filler material or riigidized preform. A structural refractory material which holds the preform is made by forming a first precursor to the supportive structural refractory material and subsequently causing the precursor to become a rigid supportive structural member. Such spontaneous infiltration occurs without the requirement for the application of any pressure or vacuum.

摘要： The present invention relates to a novel process for making a macrocomposite body. Specifically, a metal matrix composite body is first formed and thereafter, a ceramic body or a ceramic matrix composite body is caused to form from at least one surface of the already formed metal matrix composite body. The ceramic or ceramic composite body can be formed by, for example, changing from spontaneous infiltration conditions which permit a molten matrix metal to infiltrate a filler material or preform to conditions which favor the growth of a ceramic oxidation reaction product from the matrix metal (e.g., the matrix metal serves the dual role of a matrix metal and a parent metal for growth of oxidation reaction product). The growth of oxidation reaction product can occur from one or more surfaces of a metal matrix composite body and can be controlled to result in any desired shape. Moreover, the oxidation reaction product can be caused to grow directly into an atmosphere to form a ceramic body or can be caused to grow into an adjacently located filler material to form a ceramic matrix composite body. The oxidation reaction product can be formed substantially immediately after the metal matrix composite body is formed or may be formed at any point later in time.
