摘要： A predetermined quantity of a metal-matrix composite material is injected to a heating crucible along an angular infeed direction toward a location therein at which a vortex is formed by the blade of an agitator through which the material is stirred while being superheated above the melting temperature to a pouring temperature under which the melted material is transferred to a casting mold after surface skimming thereof to form a product having improved wear resistance properties.

摘要： A process for forming pressure cast alumina tile reinforced aluminum alloyrmor in which a silver coated aluminum disc is first inserted into a mold assembly, the mold assembly includes a base plate, a hollow steel die with a removable steel liner located on the base plate, a plug disposed on the base plate within the die cavity, and a punch movably disposed within the die cavity, the aluminum disc being inserted within the die cavity over the plug. Next, an alumina tile preform is prepared by cutting a plurality of alumina tiles and weaving the tiles together with a stiff steel wire. The alumina tile preform is inserted over the silver coated aluminum disc in the cavity of mold assembly. The steel die, the plug and the disc are heated. The punch is also heated separately. A melt of molten aluminum is prepared and poured into the die cavity, completely covering the alumina tile preform. The heated punch is immediately driven into the cavity to apply pressure to the molten aluminum. When the mold assembly cools, the punch is retracted, the base plate is removed, and the composite billet of pressure cast alumina tile reinforced aluminum alloy armor is removed from the mold.
摘要翻译：一种用于形成压铸铝砖瓦加强铝合金装甲的方法，其中首先将银涂覆的铝盘插入模具组件中，模具组件包括基板，具有位于基板上的可移除钢衬套的中空钢模具，设置在模腔内的基板上的插头和可移动地设置在模腔内的冲头，铝盘在插头内插入模腔内。接下来，通过切割多个氧化铝砖并用硬钢丝将织物编织在一起来制备氧化铝砖预制件。氧化铝砖预成型件插入模具组件的空腔中的银涂覆的铝盘上。钢模，插头和盘被加热。冲头也分开加热。制备熔融铝熔体并将其倒入模腔中，完全覆盖氧化铝砖预制件。加热的冲头立即被驱动到空腔中，以向熔融铝施加压力。当模具组件冷却时，冲头缩回，基板被移除，并且压模铝氧化铝砖加强铝合金装甲的复合坯料从模具中移除。

摘要： The article is produced by prepositioning nonwoven reinforcement made of aetallic mesh to which ceramic tiles are wired inside of a centrifugal casting mold. Molten matrix metal is then introduced into the mold while being rotated about an axis parallel to the inflow path of the molten metal until it completely encapsulates the reinforcement.
