    摘要： During implementing a composite metal part by compaction of an insert having reinforcing fibers in a metal body or container, gas used for compaction may enter the cavity formed in the container for receiving the insert between a lid covering the insert and the container, which can prevent or degrade compaction and diffusion welding of fiber sheaths of the insert therebetween and/or with walls of the cavity. To solve this problem, the present method includes initiating isostatic compaction by a phase including raising and maintaining temperature, followed by a phase including hot-feeding pressurized gas, and machining an assembly to obtain the part. The temperature raising phase includes a diffusion pre-welding of material rigidly connecting the pressure-adjusted walls of the lid and the container. The method can be used for designing parts having a tensile and compression resistance, such as parts for aircraft landing gear.

    摘要： The invention relates to a process for manufacturing a metal part reinforced with ceramic fibres, in which: at least one housing (10A) for an insert is machined in a metal body (10) having an upper face (10B); at least one insert (11) formed from ceramic fibres in a metal matrix is placed in the housing; the insert is covered with a cover; a vacuum is created in the interstitial space around the insert and said space is hermetically sealed under vacuum; the assembly, namely the metal body with the cover, is treated by hot isostatic pressure; and said treated assembly is machined in order to obtain said part. The process is characterized in that the cover comprises an element (12) covering the insert (11) in the slot and projecting from the upper face, and a sheet (14) covering the upper face with said element (12). In particular, the insert (11) is straight and the housing for the insert in the metal body forms a straight slot.

    摘要： A metal matrix composite preform including an angled curved groove in the surface of the matrix material. A reinforcing fiber is placed within the angled curved groove and the stiffness of the fiber causes it to be pressed against an outer wall member defining the groove. The fiber is retained within the metal matrix composite preform prior to hot isostatic pressing.
