A heterogeneous composite consisting of near-nano ceramic clusters dispersed within a ductile matrix. The composite is formed through the high temperature compaction of a starting powder consisting of a core of ceramic nanoparticles held together with metallic binder. This core is clad with a ductile metal such that when the final powder is consolidated, the ductile metal forms a tough, near-zero contiguity matrix. The material is consolidated using any means that will maintain its heterogeneous structure.

The present invention relates to the field of heat exchange technology, specifically to a composite process and system for producing a profiled microchannel plate heat exchanger. This process integrates selective laser melting additive manufacturing with micro electrical discharge machining to create microchannel plate heat exchangers featuring large aspect ratio flow channels and closed profile section flow channels. It enables the fabrication of channels with various cross-sections, such as circular and rectangular, as well as hollow closed profile section flow channels, including micro circular and square holes. The process allows for high-precision machining of microchannels with any aspect ratio. Heat exchangers produced using this composite process can endure extreme high temperatures and pressures, offering superior environmental benefits and contamination-free performance compared to conventional microchannel heat exchangers.

A wire electric discharge machining apparatus includes a machining unit that forms a product part by cutting off an outer frame portion from a workpiece and a control device that controls the machining unit. The machining unit machines a first boundary region in a boundary between the outer frame portion and the product part to leave an uncut portion, cuts off the product part from the outer frame portion by machining a second boundary region, which is the uncut portion, and repeats machining for the first/second boundary regions. When n is a natural number equal to or larger than 2, the control device sets, based on a machining state when the first boundary region is machined, different machining conditions as first machining conditions in machining the first boundary region for n-th time and second machining conditions in machining the second boundary region for n-th time.

A method for producing a hot-dip aluminum-coated steel wire, including dipping a steel wire in molten aluminum, and drawing up the steel wire from the molten aluminum, wherein at the time of drawing up the steel wire from the molten aluminum, a stabilization member is contacted with a surface of the molten aluminum and the steel wire at the boundary between the steel wire and the surface of the molten aluminum, a nozzle having a tip end of which inside diameter is 1 to 15 mm is disposed so that the tip end is positioned at a place away from the steel wire by a distance of 1 to 50 mm, and an inert gas having a temperature of 200 to 800 C. is blown out from the tip end to the boundary at a volume flow rate of 2 to 200 L/min.
