Latest Patents
Jun Ohkijima holds a patent for a method of manufacturing a metal composite material. This patent describes a process that results in a metal matrix composite material with uniformly dispersed intermetallic compounds and no micropores. The method involves forming a porous preform that includes 60% to 80% by volume fine fragments primarily made of aluminum, along with 1% to 10% by volume fine fragments of nickel, copper, or both, and 1% to 10% by volume fine fragments of titanium. The total volume of these fine fragments occupies between 62% to 95% of the preform. The preform is then infiltrated with a melt of a matrix metal selected from aluminum, aluminum alloy, magnesium, and magnesium alloy, without substantial application of pressure to the melt. This innovative method enhances the performance and durability of the resulting composite materials.
